"Partner number sexuality" (P#S) refers to how many partners individuals have/are interested in having. Those with P#S outside of monogamous desires and/or practices commonly face stigma in North America and elsewhere. Yet theories of sexuality do not always make room for diverse P#S. One theory that does is sexual configurations theory (SCT), which visually models gender/sex and sexuality (van Anders, 2015). In this study, we investigated what insights SCT could provide into P#S, whether SCT was useful to those with minoritized P#S, and how those with minoritized P#S made use of SCT. To do so, we conducted online interviews, asking participants (N = 26) to complete two SCT diagrams and report on their experience. We used template analysis to analyze transcripts and compiled "SCT heatmaps," aggregates of SCT diagrams. We constructed 11 major themes, including diverse understandings of eroticism and romantic/platonic relationships, the impacts of hermeneutical injustice (the injustice of knowledge systems) on participants' abilities to conceptualize and discuss their P#S, and how SCT facilitated conversations about P#S. The heatmaps showed that participants made use of most of both SCT diagrams, showing branchedness in P#S between "eroticism" and "nurturance," and between status, identity, and orientation. Our study highlights that the lived experience of partnering, especially of those with minoritized P#S, extends far beyond commonly understood categories, and that SCT is a useful tool that can accurately reflect diversity in P#S., Competing Interests: Declarations.

Low sexual desire in women partnered with men has been the subject of controversy and research over the past decades, including both as construct and diagnosis. Despite discussion surrounding the causes of low desire, there is a gap in research about how women themselves understand the causes of their low desire and the potential consequences of these causal attributions. In the current study, we investigated this by asking 130 women who had low desire and were partnered with men about their attributions for low desire. Through content analysis, we identified five attribution categories: psychological/individual, relational, biological, sociocultural, and/or sexual orientation/identity/status. Many participants chose more than one category, indicating a multifaceted nature of women's causes of low desire. We then quantitatively assessed women's feelings of responsibility for, and emotions surrounding, their low desire. Our findings indicate that the majority-but not all-of women have negative feelings about their low desire. However, the specific emotions they experience are related to their attribution patterns. This underscores the significance of investigating various facets of women's attributions regarding low desire in order to gain a more comprehensive understanding of their emotional experiences and desire overall., Competing Interests: Declarations.

How gender identity is assessed directly shapes how students are supported in elementary schools in the United States. Despite the existence of gender diversity, calls for more inclusive science, and recommendations from national research associations and societies to incorporate and emphasize the voices of individuals with diverse gender identities, most studies exploring gender disparities in education have relied heavily on the assumption of a gender binary. As a result, the omission of diverse gender identities from educational research in the elementary years is troubling. To address this area of need, the current article summarizes the opportunities for and constraints surrounding inclusive evaluation of gender identity in the elementary school years. We begin with a brief review of common methods used to assess gender identities for children in elementary school, including the strengths and limitations of each. We next contextualize these measures by outlining the current state-level barriers to including diverse gender identities in assessments of gender. In highlighting the best available practices and the structural systems of oppression realized through state-level policies that perpetuate an inability to represent student voices across the gender spectrum, we conclude with a call to action to inspire the evolution of best practices in the service of all students.

Feminist considerations have influenced how women and men view sex, affecting not only women's perspectives but also men's feelings about sexual desire with regard to gender equity. This might be especially the case among men who self-identify as feminist. However, how men should manage their sexual desire or communicate about it within relationships with women is not always clear in this evolving social climate. Thus, the current study aimed to explore the successes and/or struggles feminist heterosexual men experience while navigating their desires alongside feminist considerations. To explore this, we recruited feminist-identified heterosexual men in long-term relationships. We asked participants (N = 30) a series of questions regarding their sexual desire, considering the context of their long-term relationships and evolving gender norms, during a one-on-one interview via Zoom. Using thematic analysis, we identified 11 themes from the interview data. We found that, though the feminist men in this study were all aware of negative societal perceptions of heterosexual men's sexual desire, most men in this study did not feel conflicts between their feminist principles and their own sexual desires. This is because they reported already following feminist principles; those who felt ambivalent navigated this by communicating with their partners. Findings demonstrate the usefulness and positive impact men report feminism having on them, their sexuality, and their long-term relationships, by allowing them to better engage with their sexuality and partners., (© 2024.

Sexual norms define perceptions of who is acceptable to partner with, how many partners are appropriate, and what sexual behaviors are acceptable to engage in. This shapes, in part, who has access to sexual pleasure and who is minoritized based on their sexuality. Though well theorized and researched for "in-person" sexuality, much less is known about sexual norms in other contexts/modalities, such as porn use and sexual fantasy, or how norms connect across these contexts. In the present study, we investigated sexual norms in porn, fantasy, and in-person sexuality, and similarities or differences between these. In an online study, gender/sex and sexually diverse participants (N = 706) manipulated digital circles representing porn use, sexual fantasy, and in-person sexuality. They used circle overlap to represent branchedness (i.e., distinction) and coincidence (i.e., similarity) in norm content, and circle size to indicate perceived norm strength. We found evidence that norm content was perceived to be more branched (i.e., distinct) than coincident (similar) and that norm strength for each context was high. This provides evidence that when people engage in each of these sexual contexts, they tend to do so through distinct normative lenses, rather than a singular lens that represents a universal set of norms applying across all sexual situations. This has implications for how we understand the associations between porn use, fantasy, and in-person sexuality, and highlights the importance of attending to sexuality in context., (© 2024.

Psychological sexual coercion is known to negatively impact those who experience it, yet sexual encounters where orgasm is present are often presumed to be positive and absent of coercion. In the present study, we conducted an online survey with women ( n = 179) and men ( n = 251) to test associations between sexually coercive experiences that include orgasm and negative psychological, sexual, and relationship outcomes. To do so, we focused on three experiences: having an orgasm during coerced sex (CS), having a coerced orgasm during desired sex (CO), and having a coerced orgasm during coerced sex (COS). Using structural equation modeling, we found that ever having any of these coercion-plus-orgasm experiences with a current partner predicted significantly higher avoidance motivations (i.e., engaging in sex to avoid conflict with one's partner), which in turn predicted significantly worse psychological distress, sexual satisfaction, relationship satisfaction, and sexual functioning (but not dyadic sexual desire). We also found that CS, CO, and COS predicted negative outcomes to a similar degree. However, testing gender/sex as a moderator clarified that CS predicted significantly lower sexual satisfaction, sexual functioning, and sexual desire for women but not men. Furthermore, CO predicted faking orgasms in women, but COS predicted faking orgasms in men. Together, results demonstrate that experiencing psychological sexual coercion and/or orgasm coercion is significantly associated with negative outcomes even if the coerced person's orgasm occurs.

Low sexual desire in women is usually studied as a problem, one that is located within women. However, other possibilities exist, including known gender inequities related to heteronormative gender roles. In this study, we provide the first test of the theory that heteronormativity is related to low sexual desire in women partnered with men, focusing specifically on inequities in the division of household labor. In two studies with women who were partnered with men and had children (Study 1, N = 677; Study 2, N = 396), performing a large proportion of household labor was associated with significantly lower sexual desire for a partner. Together, the results suggest that this association was mediated by both perceiving the partner as a dependent and perceiving the division of labor as unfair. These results support the heteronormativity theory of low sexual desire in women partnered with men, and show that gender inequities are important, though understudied, contributors to low desire in women partnered with men., (© 2022.

Sexual orientation describes sexual interests, approaches, arousals, and attractions. People experience these interests and attractions in a number of contexts, including in-person sexuality, fantasy, and porn use, among others. The extent to which sexual orientation is divergent (branched) and/or overlapping (coincident) across these, however, is unclear. In the present study, a gender/sex and sexually diverse sample (N = 30; 15 gender/sex/ual minorities and 15 majorities) manipulated digital circles representing porn use, in-person sexuality, and fantasy on a tablet during in-person interviews. Participants used circle overlap to represent the degree of shared sexual interests across contexts and circle size to indicate the strength and/or number of sexual interests within contexts. Across multiple dimensions of sexual orientation (gender/sex, partner number, and action/behavior), we found evidence that sexual interests were both branched and coincident. These findings contribute to new understandings about the multifaceted nature of sexual orientations across contexts and provide a novel way to measure, conceptualize, and understand sexual orientation in context., (© 2022.

Trying to ensure that a partner orgasms during sex is generally seen as positive, but research has yet to assess how this might involve pressuring partners to orgasm in coercive ways. In the present study, we tested whether pressuring a partner to orgasm is a coercive behavior by assessing how this behavior overlaps with sexual coercion (i.e., pressuring someone into having sex). Participants of diverse gender/sex and sexual identities (N = 912, M age = 31.31 years, SD = 9.41) completed an online survey that asked them whether they had ever felt pressured by a partner to orgasm, to describe what partners have said or done to pressure them, and to answer a series of questions about the most recent incident in which this occurred. Mixed quantitative and qualitative results showed that orgasm pressure tactics were analogous to sexual coercion tactics and that being pressured to orgasm was associated with experiencing sexual coercion, faking orgasms, and negative psychological and relationship outcomes. Together, findings challenge the assumption that trying to ensure a partner's orgasm occurrence is necessarily positive and demonstrate that orgasm coercion exists., (© 2021.

Low sexual desire in women partnered with men is typically presumed to be a problem-one that exists in women and encourages a research agenda on causation and treatment targeting women. In this paper, we present a distinct way forward for research on low sexual desire in women partnered with men that attends to a more structural explanation: heteronormativity. A heteronormative worldview assumes that relationships and structures are heterosexual, gender (usually conflated with sex) is binary and complementary, and gender roles fit within narrow bounds including nurturant labor for women. We propose the heteronormativity theory of low sexual desire in women partnered with men, arguing that heteronormative gender inequities are contributing factors. We outline four hypotheses and their predictions related to: inequitable divisions of household labor, blurring of partner and mother roles, objectification of women, and gender norms surrounding sexual initiation. We discuss some mechanisms-social, physiological, and otherwise-for the heteronormativity theory, especially related to stress, objectification, and nurturance. We close by noting some limitations of our paper and the ways that the heteronormativity theory of low sexual desire in women partnered with men provides a rigorous, generative, and empirical way forward., (© 2021.

Orgasm coercion involves pressuring a partner to orgasm by implying that not orgasming will have negative consequences. In the present study, we used mixed methods to explore (1) how various individual and contextual factors-i.e., frequency of orgasm coercion, orgasm frequency, gender/sex, sexual identity, the orgasm coercion tactics used, and perceptions of the perpetrator's intention-affect relationship and psychological outcomes associated with orgasm coercion, and (2) how different individuals characterize these outcomes. Cisgender women, cisgender men, and gender/sex minority participants (N = 308, M age = 30.44 years, SD = 8.16) described the most recent encounter in which they experienced orgasm coercion and then rated and described the positive and negative relationship and psychological outcomes associated with the incident. Quantitative results showed that the following predicted significantly higher negative relationship and psychological outcomes: a higher frequency of experiencing orgasm coercion, lower frequency of orgasming with partners in general, and experiencing orgasm coercion via physical or emotional threats. Believing that the perpetrator was motivated by altruism or social pressures mitigated these effects. And, experiencing orgasm coercion via implied fault predicted significantly higher negative relationship outcomes only for cisgender women. Additionally, being a sexual minority predicted higher negative relationship (but not psychological) outcomes, whereas being a gender/sex minority predicted higher negative psychological (but not relationship) outcomes. Qualitative results showed that relationship and psychological outcomes varied; for example, participants discussed making a partner happy, disappointment with their partner's behaviors, ending the relationship, and lasting feelings of anxiety, guilt, and abuse. Together, findings offer new insights into how orgasm coercion affects those who experience it., (© 2021.

Background: Gender euphoria is an important experience and concept for many, especially transgender and/or nonbinary individuals, but has not received much attention from psychological and clinical research. In contrast to gender dysphoria , which originates in psychiatry, the term "gender euphoria" has been mobilized by some LGBTQ people to describe the powerfully positive emotions that can come from one's gender/sex. As such, researchers and clinicians may benefit from conceptual clarity as to what gender euphoria is and what kinds of experiences might result in gender euphoria., Aim: We aimed to better understand how trans community members and others conceptualize the term "gender euphoria," including its relationship to gender dysphoria, as well as the contexts and behaviors that elicit gender euphoria., Method: We administered an online qualitative survey to participants ( N  = 47) of diverse sexualities and gender/sexes (including transgender, cisgender, and/or nonbinary participants) who had heard of or used the term "gender euphoria." Participants answered open-ended questions about where they had heard the term being used, how they would define gender euphoria and gender dysphoria, the relation between these terms, and their gender euphoric experiences., Results: Analyses resulted in five themes: (1) gender euphoria describes a joyful feeling of rightness in one's gender/sex, (2) gender euphoric experiences can be external, internal, and/or social, (3) "gender euphoria" originated in and circulates in online and in-person gender/sex minority communities, (4) dysphoria describes a negative feeling of conflict between gender/sexed aspects of one's self, and (5) the relationship between euphoria and dysphoria is complex., Discussion: These results can inform qualitative and quantitative research, gender affirmative clinical practice, political fights for transgender rights, and understandings of gendered experiences for people of all identities., Competing Interests: The authors declare that they have no conflicts of interest., (© 2021 Taylor & Francis Group, LLC.)

Gender/sex and sexual diversity are increasingly understood by the public as complex. But, scientific frameworks that address the complexity of gender/sex and sexual diversity are few and not well situated for the public. Sexual configurations theory (SCT; van Anders, 2015) is one approach that provides a visual framework for understanding and measuring gender/sex and sexual diversity. But how might knowledge users and creators actually use it? To make SCT more accessible to researchers, educators, clinicians, and the general public, we created three instructional videos (individual gender/sex, gender/sex sexuality, and partner number sexuality) that explained SCT and demonstrated how to use its diagrams. Participants (N = 242) of diverse gender/sex and sexual identities, including professionals who work in gender/sex- and sexuality-related fields, watched one of the three videos, filled out the diagrams, and evaluated the video and diagrams via scaled and open-ended questions. Results demonstrated that the SCT videos were sufficient for most participants to fill out the diagrams. Participants evaluated the video generally positively, with some variation by condition, identity group, and professional status. These results indicate that instructional videos are able to translate SCT, potentially facilitating uptake of SCT by clinicians, researchers, and educators as well as increasing awareness of gender/sex and sexual diversity more broadly within the public.

Orgasms during consensual sex are often assumed to be wholly positive experiences. This assumption overshadows the possibility that orgasm experiences during consensual sex could be "bad" (i.e., negative and/or non-positive). In the present study, we employed an online survey to explore the possibility that orgasm experiences could be "bad" during consensual sex by asking participants of diverse gender and sexual identities (N = 726, M age = 28.42 years, SD = 7.85) about a subset of potential bad orgasm experiences. Specifically, we asked participants whether they have ever had an orgasm during coerced sex, compliant sex, and/or when they felt pressured to have an orgasm (i.e., orgasm pressure). We also asked participants who had such an experience to describe it, resulting in qualitative descriptions from 289 participants. Using mixed quantitative and qualitative analyses, we found compelling evidence that orgasm experiences can be "bad" during consensual sex. Specifically, many participants described their experiences in negative and/or non-positive ways despite orgasm occurrence, reported that their orgasms were less pleasurable compared to other experiences, and suggested that their orgasm experiences had negative impacts on their relationships, sexuality, and/or psychological health. Participants also suggested that social location shaped their bad orgasm experiences, citing gender and sexual identity, gender identity conflict, race/ethnicity, and religion as important to their perceptions of and responses to their experiences. Results directly challenge the assumption that orgasms during consensual sex are always and/or unilaterally positive experiences.

Recent research on gender and sexual majority individuals suggests that their attractions, identities, and experiences may not be as homogenous or easily generalizable as is often assumed. Sexual configurations theory (SCT; van Anders, 2015) is a framework for conceptualizing individuals' partnered sexualities and gender/sexes with a focus on gender/sex and sexual diversity. SCT has been successfully used in recent empirical work with gender and sexual minority individuals (Schudson, Manley, Diamond, & van Anders, 2018), but it has not yet been tested with heterosexual, cisgender individuals. In the present study, we tested the use of SCT in qualitative interviews with 26 gender and sexual majority participants to address the following research questions: What are the strengths and weaknesses of SCT for representing heterosexual, cisgender individuals' gender/sexes and partnered sexualities? How do gender and sexual majority individuals use SCT to express their gender/sexes and partnered sexualities? And, what insights about sexual and gender diversity can be gained from using SCT with a gender and sexual majority sample? Using thematic analysis, we evaluated how participants interacted with SCT and the SCT diagrams. Results showed that our participants used components of SCT to convey comprehensive and nuanced interests, which included gender/sex and sexual diversity outside of what is typically expected in research on heterosexual, cisgender individuals. We discuss findings and challenges specific to working with majority participants and offer implications for future work on gender/sex and sexual majorities and on gender/sex and sexual diversity in general.

The view that humans comprise only two types of beings, women and men, a framework that is sometimes referred to as the "gender binary," played a profound role in shaping the history of psychological science. In recent years, serious challenges to the gender binary have arisen from both academic research and social activism. This review describes 5 sets of empirical findings, spanning multiple disciplines, that fundamentally undermine the gender binary. These sources of evidence include neuroscience findings that refute sexual dimorphism of the human brain; behavioral neuroendocrinology findings that challenge the notion of genetically fixed, nonoverlapping, sexually dimorphic hormonal systems; psychological findings that highlight the similarities between men and women; psychological research on transgender and nonbinary individuals' identities and experiences; and developmental research suggesting that the tendency to view gender/sex as a meaningful, binary category is culturally determined and malleable. Costs associated with reliance on the gender binary and recommendations for future research, as well as clinical practice, are outlined. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Sexuality research has generally privileged attractions based on partners' sexed physical bodies over attractions based on other features, including gender expression and personality traits. Gender may actually be quite central to sexual attractions. However, its role has received little empirical attention. To explore how gendered and sexed features, among others, are related to sexual attractions, the current study assessed how sexually diverse individuals described their attractions to feminine, masculine, and gender-nonspecific features of women and men. A sample of 280 individuals responded to the open-ended questions: "What do you find attractive in a man?" and "What do you find attractive in a woman?" We coded responses as pertaining to physical and/or psychological features, and as being gendered masculine, feminine, or gender-nonspecific. Our analyses showed that participants named gender-nonspecific features most frequently in responses to both questions, feminine features more than masculine features in attractions to women, and masculine features more than feminine features in attractions to men. Additionally, participants named feminine physical features more than masculine physical features, and masculine psychological features more than feminine psychological features, both in their attractions to women and overall. These results highlight the importance of considering attractions based on gender, rather than sex alone.

Sexual desire and testosterone are widely assumed to be directly and positively linked to each other despite the lack of supporting empirical evidence. The literature that does exist is mixed, which may result from a conflation of solitary and dyadic desire, and the exclusion of contextual variables, like stress, known to be relevant. Here, we use the Steroid/Peptide Theory of Social Bonds as a framework for examining how testosterone, solitary and partnered desire, and stress are linked over time. To do so, we collected saliva samples (for testosterone and cortisol) and measured desire as well as other variables via questionnaires over nine monthly sessions in 78 women and 79 men. Linear mixed models showed that testosterone negatively predicted partnered desire in women but not men. Stress moderated associations between testosterone and solitary desire in both women and men, but differently: At lower levels of stress, higher average testosterone corresponded to higher average solitary desire for men, but lower solitary desire on average for women. Similarly, for partnered desire, higher perceived stress predicted lower desire for women, but higher desire for men. We conclude by discussing the ways that these results both counter presumptions about testosterone and desire but fit with the existing literature and theory, and highlight the empirical importance of stress and gender norms.

Sexual desire is typically measured as a unitary erotic phenomenon and is often assumed by biological and biomedical researchers, as well as the lay public, to be directly connected to physiological parameters like testosterone (T). In the present study, we empirically examined how conceptualizing sexual desire as multifaceted might clarify associations with T and contextual variables. To do so, we used the Sexual Desire Questionnaire (DESQ), which assesses multifaceted dyadic sexual desire, to explore how contextual variables such as social location, relationship status, and desire target (e.g., partner vs. stranger) might be meaningful for reports of sexual desire and associated hormonal correlations. We focused on women (N = 198), because sexual desire and testosterone are generally unlinked in healthy men. Participants imagined a partner or stranger while answering the 65 DESQ items and provided a saliva sample for hormone assay. Analyses showed that the DESQ factored differently for the current sample than in previous research, highlighting how sexual desire can be constructed differently across different populations. We also found that, for the Intimacy, Eroticism, and Partner Focus factors, mean scores were higher when the desire target was a partner relative to a stranger for participants in a relationship, but equally high between partner versus stranger target for single participants. DESQ items resolved into meaningful hormonal desire components, such that high endorsement of Fantasy Experience was linked to higher T, and higher cortisol was linked with lower endorsement of the Intimacy factor. We argue that conceptualizing desire as multifaceted and contextualized when assessing hormonal links-or questions in general about desire-can clarify some of its complexities and lead to new research avenues.

Orgasms have been promoted as symbols of sexual fulfillment for women, and have perhaps become the symbol of a woman's healthy sex life. However, some research has suggested that this focus on women's orgasms, though ostensibly for women, may actually serve men; but the mechanisms of this are unclear. In the present experiment, we hypothesized that women's orgasms specifically function as a masculinity achievement for men. To test this, we randomly assigned 810 men (M age = 25.44, SD = 8.31) to read a vignette where they imagined that an attractive woman either did or did not orgasm during a sexual encounter with them. Participants then rated their sexual esteem and the extent to which they would feel masculine after experiencing the given situation. Our results showed that men felt more masculine and reported higher sexual esteem when they imagined that a woman orgasmed during sexual encounters with them, and that this effect was exacerbated for men with high masculine gender role stress. These results suggest that women's orgasms do function-at least in part-as a masculinity achievement for men.

Sexual desire is increasingly understood to be multifaceted and not solely erotically oriented, but measures are still generally unitary and eroticism-focused. Our goals in this article were to explore the multifaceted nature of sexual desire and develop a measure to do so, and to determine how multifaceted sexual desire might be related to gender/sex and sexual orientation/identity. In the development phase, we generated items to form the 65-item Sexual Desire Questionnaire (DESQ). Next, the DESQ was administered to 609 women, 705 men, and 39 non-binary identified participants. Results showed that the DESQ demonstrated high reliability and validity, and that sexual desire was neither unitary nor entirely erotic, but instead was remarkably multifaceted. We also found that multifaceted sexual desire was in part related to social location variables such as gender/sex and sexual orientation/identity. We propose the DESQ as a measure of multifaceted sexual desire that can be used to compare factor themes, total scores, and scores across individual items in diverse groups that take social context into account. Results are discussed in light of how social location variables should be considered when making generalizations about sexual desire, and how conceptualizations of desire as multifaceted may provide important insights.

Solitary and partnered sexuality are typically depicted as fundamentally similar, but empirical evidence suggests they differ in important ways. We investigated how women's definitions of sexual pleasure overlapped and diverged when considering solitary versus partnered sexuality. Based on an interdisciplinary literature, we explored whether solitary pleasure would be characterized by eroticism (e.g., genital pleasure, orgasm) and partnered pleasure by nurturance (e.g., closeness). Via focus groups with a sexually diverse sample of women aged 18-64 (N = 73), we found that women defined solitary and partnered pleasure in both convergent and divergent ways that supported expectations. Autonomy was central to definitions of solitary pleasure, whereas trust, giving pleasure, and closeness were important elements of partnered pleasure. Both solitary and partnered pleasure involved exploration for self-discovery or for growing a partnered relationship. Definitions of pleasure were largely similar across age and sexual identity; however, relative to queer women, heterosexual women (especially younger heterosexual women) expressed greater ambivalence toward solitary masturbation and partnered orgasm. Results have implications for women's sexual well-being across multiple sexual identities and ages, and for understanding solitary and partnered sexuality as overlapping but distinct constructs.

Sexual thoughts are sufficient to increase testosterone (T) in women, yet erotic films are not. A key confound in past studies is autonomy in stimulus selection: women choose the content of their sexual thoughts but films have been selected by researchers. We hypothesized that self-chosen erotic films, compared to researcher-chosen erotic films, would (1) increase women's self-reported arousal, enjoyment, and identification with stimuli, and decrease negative affect; and (2) increase T. Participants (N = 116 women) were randomly assigned to a neutral documentary condition or one of three erotic film conditions: high choice (self-chosen erotica from participants' own sources), moderate choice (self-chosen erotica from films preselected by sexuality researchers), or no choice (researcher-chosen erotica). Participants provided saliva samples for T before and after viewing the film in the privacy of their homes. Compared to researcher-chosen erotica, self-chosen erotica increased self-reported arousal and enjoyment, but also unexpectedly disgust, guilt, and embarrassment. Self-chosen erotica only marginally increased identification with stimuli compared to researcher-chosen erotica. Overall, film condition did not affect T, but individual differences in identification moderated T responses: among women reporting lower levels of identification, the moderate choice condition decreased T compared to the no choice condition, but this difference was not observed among women with higher identification. These results highlight the importance of cognitive/emotional factors like identification for sexually modulated T. However, self-chosen erotica results in more ambivalent rather than unequivocally positive cognitive/emotional responses, perhaps because stigma associated with viewing erotica for women becomes more salient when choosing stimuli.

Testosterone is typically understood to contribute to maleness and masculinity, although it also responds to behaviors such as competition. Competition is crucial to evolution and may increase testosterone but also is selectively discouraged for women and encouraged for men via gender norms. We conducted an experiment to test how gender norms might modulate testosterone as mediated by two possible gender→testosterone pathways. Using a novel experimental design, participants (trained actors) performed a specific type of competition (wielding power) in stereotypically masculine vs. feminine ways. We hypothesized in H1 (stereotyped behavior) that wielding power increases testosterone regardless of how it is performed, vs. H2 (stereotyped performance), that wielding power performed in masculine but not feminine ways increases testosterone. We found that wielding power increased testosterone in women compared with a control, regardless of whether it was performed in gender-stereotyped masculine or feminine ways. Results supported H1 over H2: stereotyped behavior but not performance modulated testosterone. These results also supported theory that competition modulates testosterone over masculinity. Our findings thus support a gender→testosterone pathway mediated by competitive behavior. Accordingly, cultural pushes for men to wield power and women to avoid doing so may partially explain, in addition to heritable factors, why testosterone levels tend to be higher in men than in women: A lifetime of gender socialization could contribute to "sex differences" in testosterone. Our experiment opens up new questions of gender→testosterone pathways, highlighting the potential of examining nature/nurture interactions and effects of socialization on human biology.

Sexual orientation typically describes people's sexual attractions or desires based on their sex relative to that of a target. Despite its utility, it has been critiqued in part because it fails to account for non-biological gender-related factors, partnered sexualities unrelated to gender or sex, or potential divergences between love and lust. In this article, I propose Sexual Configurations Theory (SCT) as a testable, empirically grounded framework for understanding diverse partnered sexualities, separate from solitary sexualities. I focus on and provide models of two parameters of partnered sexuality--gender/sex and partner number. SCT also delineates individual gender/sex. I discuss a sexual diversity lens as a way to study the particularities and generalities of diverse sexualities without privileging either. I also discuss how sexual identities, orientations, and statuses that are typically seen as misaligned or aligned are more meaningfully conceptualized as branched or co-incident. I map out some existing identities using SCT and detail its applied implications for health and counseling work. I highlight its importance for sexuality in terms of measurement and social neuroendocrinology, and the ways it may be useful for self-knowledge and feminist and queer empowerment and alliance building. I also make a case that SCT changes existing understandings and conceptualizations of sexuality in constructive and generative ways informed by both biology and culture, and that it is a potential starting point for sexual diversity studies and research.

Testosterone is thought to be positively associated with "mating effort", or the initiation and establishment of sexual relationships (Wingfield et al., 1990). Yet, because testosterone is negatively associated with nurturance (van Anders et al., 2011), high levels of testosterone may be incompatible with relationship maintenance. For instance, partnered men with high testosterone report lower relationship quality compared to partnered men with low testosterone (e.g., Booth and Dabbs, 1993). Findings for women are inconsistent, however, and even less is known about potential dyadic associations between testosterone and relationship quality in couples. In the current report, we assessed relationship satisfaction, commitment, and investment in heterosexual couples and tested the hypothesis that these aspects of relationship quality would be negatively associated with an individual's own and his/her partner's testosterone levels. We found that testosterone was in fact negatively associated with relationship satisfaction and commitment in both men and women. There was also evidence for dyadic associations: Participants' satisfaction and commitment were negatively related to their partners' levels of testosterone, and these associations were larger for women's than men's testosterone. Our findings are consistent with the idea that high testosterone may be incompatible with the maintenance of nurturant relationships. The current findings also provide some of the first evidence for dyadic associations between testosterone and relationship quality in couples, highlighting the interdependent nature of close relationship processes and the importance of considering this interdependence in social neuroendocrine research., (Published by Elsevier Inc.)

Testosterone (T) and other androgens are incorporated into an increasingly wide array of human sexuality research, but there are a number of issues that can affect or confound research outcomes. This review addresses various methodological issues relevant to research design in human studies with T; unaddressed, these issues may introduce unwanted noise, error, or conceptual barriers to interpreting results. Topics covered are (1) social and demographic factors (gender and sex; sexual orientations and sexual diversity; social/familial connections and processes; social location variables), (2) biological rhythms (diurnal variation; seasonality; menstrual cycles; aging and menopause), (3) sample collection, handling, and storage (saliva vs. blood; sialogogues, saliva, and tubes; sampling frequency, timing, and context; shipping samples), (4) health, medical issues, and the body (hormonal contraceptives; medications and nicotine; health conditions and stress; body composition, weight, and exercise), and (5) incorporating multiple hormones. Detailing a comprehensive set of important issues and relevant empirical evidence, this review provides a starting point for best practices in human sexuality research with T and other androgens that may be especially useful for those new to hormone research.

Research links explicit sexuality (e.g., physical attraction and pleasure) to high testosterone (T) and nurturance (loving contact) to low T. Engaging in sexual fantasy, which can include explicit sexual and nurturant elements, increases T in women but not in men. We examined whether individual differences in the explicit sexual and nurturant content of fantasy were linked with T or with estradiol (E2). In addition, we explored whether fantasy content differed or overlapped by gender/sex. Participants (26 women, 23 men) provided saliva samples for hormones before and after imagining a self-defined positive sexual encounter and responding to open-ended questions about the situation they imagined. We systematically content-coded responses for explicit sexual and nurturant content. In men, lower inclusion of nurturant content predicted larger T responses to fantasy. Fantasy content was not linked with T in women or with E2 in women or men. Women and men did not differ significantly in explicit sexual and nurturant content. Our findings suggest that individual experiences of fantasy as more or less nurturant affect T in men, provide support for the Steroid/Peptide Theory of Social Bonds, and highlight the value of integrating hormones and content analysis to investigate research questions relevant to sexuality and gender/sex.

Introduction: Research on postpartum sexuality has focused primarily on mothers, though new findings suggest that relational perceptions may have a strong influence over sexual desire and behavior. Little investigation exists regarding sexuality in partners of postpartum women. Additionally, recent findings point to the importance of a partner's sexuality for postpartum women's perceptions of their own sexuality in this time., Aims: The goal of this research was to explore women's partners' sexuality in the early postpartum phase taking into account psychosocial context., Methods: Partners (N = 114; 95 men, 18 women, 1 unspecified) of postpartum women completed a retrospective online questionnaire about their sexuality during the 3 months following their youngest child's birth., Main Outcome Measures: Primary measures included sexual desire (Sexual Desire Inventory), latency to sexual behavior, and enjoyment and initiation of sexual behavior. Other psychosocial variables were investigated: partners' perceptions of the birth mother's sexual desire, perceptions of the birth experience (Questionnaire Measuring Attitudes About Labor and Delivery), postpartum stress (Perceived Stress Scale), body image self-consciousness (Body Image Self-Consciousness Scale), social support (Multidimensional Scale of Perceived Social Support), fatigue, and experiences surrounding breastfeeding., Results: Partners reported most frequent engagement in intercourse in the postpartum period, earliest engagement in masturbation, and highest enjoyment of receiving oral sex compared with other sexual activities. Partners' sexual desire was not correlated with the psychosocial variables measured in the study. Findings for partners' sexuality were similar by gender, except for perceptions of social support and likelihood to engage in intercourse., Conclusions: This study provided a novel perspective on the study of postpartum sexuality by investigating physical and psychosocial influences on the experiences of partners of parous women. Given parallels between sexuality reported by partners in this study and by birth mothers in past studies, this study provided evidence that sexuality in the postpartum period may be experienced similarly, highlighting the social and relational nature of the postpartum., (© 2013 International Society for Sexual Medicine.)

Largely based on pre-theory that ties high testosterone (T) to masculinity, and low T to femininity, high T is mainly studied in relation to aggression, mating, sexuality, and challenge, and low T with parenting. Evidence, however, fails to support this, and the social variability in T is better accounted for by a competition-nurturance trade-off as per the Steroid/Peptide Theory of Social Bonds (van Anders et al., 2011). Four key domains are discussed: adult-infant interactions, sexual desire, sexual behavior, and partnering. Empirical engagements with gender/sex are shown to lead to important insights over assumptions about masculinity-femininity. Humans are discussed within a comparative framework that attends to cross-species principles informed by human insights alongside human-specific particularities like social constructions, which are critical to evolutionary understandings of the social role of T. This paper thus integrates seemingly orthogonal perspectives to allow for transformative approaches to an empirically-supported social phenomenology of T., (Copyright © 2013 Elsevier Inc.

Touch is a critical factor in intimate bonds between romantic partners. Although cuddling is a key expression of intimacy, it has received little empirical attention. Past research suggests that cuddling has some sexual aspects (e.g., it increases testosterone [T]), but there are theoretical reasons to expect cuddling to also involve nurturant intimacy (which should decrease T). In this article, we examined the phenomenon of partner cuddling to: (1) provide a descriptive examination; (2) determine if cuddling involved only nurturant intimacy or also sexual intimacy; and (3) test whether cuddling was perceived as nurturant but experienced as sexual. Via an online questionnaire, 514 participants (338 women) responded to quantitative and qualitative questions about cuddling with their romantic partners. Results suggested that cuddling occurred frequently and for relatively long durations, and was viewed very positively. Findings also showed that cuddling was perceived as nurturant and non-sexual but was experienced as at least somewhat sexual, which may explain why past research had found that cuddling increased T. Correlational analyses linked cuddling frequency and enjoyment positively with partnered sexual activities, but negatively with solitary sexuality. Results were discussed relative to evolutionary theories of distinct but overlapping neurobiological systems underlying pair bonding that involve sexual and nurturant intimacy.

Sexual desire is typically higher in men than in women, with testosterone (T) thought to account for this difference as well as within-sex variation in desire in both women and men. However, few studies have incorporated both hormonal and social or psychological factors in studies of sexual desire. The present study addressed how three psychological domains (sexual-relational, stress-mood, body-embodiment) were related to links between T and sexual desire in healthy adults and whether dyadic and solitary desire showed associations with T. Participants (n = 196) were recruited as part of the Partnering, Physiology, and Health study, which had 105 men and 91 women who completed questionnaires and provided saliva for cortisol and T assays. T was positively linked to solitary desire in women, with masturbation frequency influencing this link. In contrast, T was negatively correlated with dyadic desire in women, but only when cortisol and perceived social stress were controlled. Replicating past findings, no significant correlations between T and desire in men were apparent, but these analyses showed that the null association remained even when psychological and confound variables were controlled. Men showed higher desire than women, but masturbation frequency rather than T influenced this difference. Results were discussed in terms of challenges to assumptions of clear links between T and desire, gendered approaches to T, and the unitarity of desire.

Sexual stimuli increase testosterone (T) or cortisol (C) in males of a variety of species, including humans, and just thinking about sex increases T in women. We investigated whether sexual thoughts change T or C in men and whether hormone measures (baseline, post-activity, and changes) correlate with psychological sexual arousal. We used the Imagined Social Situation Exercise to assess how hormones respond to and correlate with sexual thoughts and arousal relative to three control conditions: neutral, stressful, and positive. A total of 99 men provided a baseline saliva sample, imagined and wrote about a sexual or control situation, and provided a second saliva sample 15 min later. Results indicated that, for participants in the sexual condition, higher baseline and post-activity C corresponded to larger increases in self- reported sexual and autonomic arousal. Although sexual thoughts increased sexual arousal, they did not change T or C compared to control conditions. Our results suggest that sexual thoughts are not sufficient to change T or C in men, but C may facilitate sexual arousal by directing energy towards a sexual situation.

Introduction: Traditionally, sexual desire is understood to occur spontaneously, but more recent models propose that desire responds to sexual stimuli., Aims: To experimentally assess whether sexual stimuli increased sexual desire; to compare how sexual arousal and desire responded to three modalities of sexual stimuli: erotic story, unstructured fantasy, and the Imagined Social Situation Exercise (ISSE)., Methods: In an online study, participants (128 women, 98 men) were randomly assigned to one of four arousal conditions (ISSE, story, fantasy, or neutral), and then completed desire measures. In the ISSE, participants imagined and wrote about a positive sexual encounter with a self-defined attractive person., Main Outcome Measures: Sexual arousal (perceived genital, psychological, and perceived autonomic), anxiety, positive and negative affect, and state sexual desire via self-report measures pre- and post-condition; "trait" desire via the Sexual Desire Inventory post-condition., Results: All three sexual conditions significantly increased sexual arousal and positive affect compared with the neutral condition, with trends for higher arousal to unstructured fantasy than the ISSE or story conditions. Sexual conditions significantly increased scores on state measures of sexual desire. In addition, sexual context influenced measurement of "trait" solitary sexual desire in women, such that women reported significantly higher trait desire after the neutral and ISSE conditions vs. fantasy., Conclusion: Results highlight the responsiveness of sexual desire, problems with measurement of desire as a long-term trait, trade-offs of using the ISSE and other stimuli in sexuality research, and the need to address context in discussions of women's and men's desire., (© 2012 International Society for Sexual Medicine.)

Introduction: Women's postpartum sexuality can be influenced by factors related to physical, personal, and relationship transitions after the newborn arrives. Despite this, many experiential and social factors remain unexplored., Aims: This study aims to (i) investigate a range of variables thought to influence postpartum sexuality; (ii) expand the focus beyond latency to penis-vagina intercourse; and (iii) assess positive aspects of postpartum sexuality., Methods: Via retrospective reporting on the first 3 months postpartum, 304 women completed an online questionnaire., Main Outcome Measures: The main outcome measures were retrospective reports of sexual desire (Sexual Desire Inventory), latency to resumption of sexual activity, and perceptions of partner's sexual desire. Other measures were birth experience (Questionnaire Measuring Attitudes About Labor and Delivery), breastfeeding status, perceptions of social support (Multidimensional Scale of Perceived Social Support), stress (Perceived Stress Scale), and body image (Body Image Self-Consciousness Scale)., Results: Significant differences in time to resumption were found. Women performed oral sex on their partners earlier than engaging in masturbation, which was followed by intercourse and then receiving oral sex. Post hoc analyses identified birth experience, social support, importance of partner's sexual fulfillment, and perception of partner's desire as contributors to this pattern. Women's postpartum sexual desire was influenced by their perceptions of their partner's postpartum sexuality and individual's level of fatigue. Results suggested that postpartum desire was not significantly influenced by breastfeeding status, vaginal issues, or psychosocial variables including stress, body image, or social support., Conclusion: Results suggest that women's perceptions of their partner's sexuality impact postpartum sexuality more than the physical factors most commonly studied (e.g., vaginal trauma and breastfeeding). These results portray postpartum sexuality as a multidimensional phenomenon and highlight the need for further research that addresses its social context., (© 2012 International Society for Sexual Medicine.)

Introduction: Higher testosterone (T) is tied to risk-taking, especially in financial domains but also in health domains relevant to acquiring sexually transmitted infections (STIs). However, safer sex constructs could themselves carry the possibility of "social risk" due to sexual stigma or embarrassment, or could involve boldness or confidence because they could represent status displays of frequent sexual activity., Aim: To determine how T and behaviorally relevant attitudes about sexual risk-taking are linked, to better understand biopsychosocial aspects of sexual health related to STIs., Methods: In 78 first-year male college students, we examined correlations between salivary T and behaviorally relevant safer sex attitudes assessed via questionnaires., Main Outcome Measures: T, via saliva; safer sex attitudes, via a composite and the University of California, Los Angeles Multidimensional Condom Attitudes Scale (MCAS)., Results: Higher T was significantly correlated with higher scores on the following: safer sex likelihood composite, r(73)=0.33, P=0.003; the MCAS safer sex resilience, r(32)=0.36, P=0.037; and the MCAS condom purchase comfort, r(32)=0.37, P=0.031. Associations between T and safer sex likelihood and resilience were still robust after controlling for potential confounds, though the association between T and purchase comfort diminished to a trend., Conclusions: Higher T was positively linked with safer sex attitudes, especially those most closely tied to STI risk avoidance. Thus, future research and interventions for STI prevention should address the possibility that safer sex may be paradoxically perceived as a "bold" or "risky" choice even as it decreases STI risk., (© 2011 International Society for Sexual Medicine.)

Testosterone (T) is generally theorized within a trade-off framework that contrasts parenting and low T with competitive challenges and high T. Paradoxically, baby cues increase T, prompting questions of whether T or its behavioral expression has been mischaracterized. We tested 55 men using a novel interactive infant doll paradigm, and results supported our hypotheses: We showed for the first time that baby cries do decrease T in men, but only when coupled with nurturant responses. In contrast, baby cries uncoupled from nurturant responses increased T. These findings highlight the need to partition infant cues and interactions into nurturant versus competitive-related contexts to more accurately conceptualize T, as per the Steroid/Peptide Theory of Social Bonds. This experiment also supports the utility of this paradigm for studying effects of infant interactions on hormonal responses, which may provide critical insights into ameliorating the darker sides of caregiving (e.g. anger, frustration, violence) and enhancing the positive sides (e.g. intimacy, nurturance, reward)., (Copyright © 2011 Elsevier Inc.

Hormones, and hormone responses to social contexts, are the proximate mechanisms of evolutionary pathways to pair bonds and other social bonds. Testosterone (T) is implicated in tradeoffs relevant to pair bonding, and oxytocin (OT) and arginine vasopressin (AVP) are positively tied to social bonding in a variety of species. Here, we present the Steroid/Peptide Theory of Social Bonds (S/P Theory), which integrates T and peptides to provide a model, set of predictions, and classification system for social behavioral contexts related to social bonds. The S/P Theory also resolves several paradoxes apparent in the literature on social bonds and hormones: the Offspring Defense Paradox, Aggression Paradox, and Intimacy Paradox. In the S/P Theory, we partition aggression into antagonistic and protective aggression, which both increase T but exert distinct effects on AVP and thus social bonds. Similarly, we partition intimacy into sexual and nurturant intimacy, both of which increase OT and facilitate social bonds, but exert distinct effects on T. We describe the utility of the S/P Theory for classifying 'tricky' behavioral contexts on the basis of their hormonal responses using partner cuddling, a behavior which is assumed to be nurturant but increases T, as a test case of the S/P Theory. The S/P Theory provides a comparative basis for conceptualizing and testing evolved hormonal pathways to pair bonds with attention to species, context, and gender/sex specificities and convergences., (Copyright © 2011 Elsevier Ltd.

Previous research suggests that sexual stimuli increase testosterone (T) in women and shows inconsistent effects of sexual arousal on cortisol (C), but effects of cognitive aspects of arousal, rather than behaviors or sensory stimuli, are unclear. The present study examined whether sexual thoughts affect T or C and whether hormonal contraceptive (HC) use moderated this effect, given mixed findings of HC use confounding hormone responses. Participants (79 women) provided a baseline saliva sample for radioimmunoassay. We created the Imagined Social Situation Exercise (ISSE) to test effects of imagining social interactions on hormones, and participants were assigned to the experimental (sexual) or one of three control (positive, neutral, stressful) conditions. Participants provided a second saliva sample 15 min post-activity. Results indicated that for women not using HCs, the sexual condition increased T compared to the stressful or positive conditions. In contrast, HC using women in the sexual condition had decreased T relative to the stressful condition and similar T to the positive condition. The effect was specific to T, as sexual thoughts did not change C. For participants in the sexual condition, higher baseline T predicted larger increases in sexual arousal but smaller increases in T, likely due to ceiling effects on T. Our results suggest that sexual thoughts change T but not C, baseline T levels and HC use may contribute to variation in the T response to sexual thoughts, and cognitive aspects of sexual arousal affect physiology., (Copyright © 2010 Elsevier Inc.
