Women often expect to encounter negative, problematic content when they consume pornography, yet many women use and enjoy pornography anyway. Some research has centered content type (e.g., sexist/violent vs. nonsexist/women-focused) as a key determinant of women's pornography experiences, but this precludes the notion that women are active, engaged consumers of pornography and minimizes women's role in shaping their own experiences. In the present study, we explored how a sample of sexually diverse women in the U.S. (aged 18-64; N = 73) worked toward positive experiences with pornography via active negotiation with negative content, using a secondary analysis of focus group data on women's sexual pleasure. We found that, although women often experienced pornography as risky, many women used it anyway and actively employed strategies to increase the likelihood of having a positive experience. Women's strategies were similar across sexual identity and age groups, but the heteronormative, youth-oriented portrayals of sexuality in mainstream pornography presented unique concerns for heterosexual, queer, and older women. Results have implications for how women can be conceptualized as active, rather than passive, consumers of pornography as well as for how women's agency might influence women's arousal responses to sexually explicit stimuli in research.

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.

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.

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.

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: 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.)

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.

Cross-cultural evidence links pair bonding and testosterone (T). We investigated what factors account for this link, how casual relationships are implicated, and whether gender/sex moderates these patterns in a North American sample. We gathered saliva samples for radioimmunoassay of T and self-report data on background, health, and social/relational variables from 115 women and 120 men to test our predictions, most of which were supported. Our results show that singles have higher T than long-term (LT) partnered individuals, and that casual relationships without serious romantic commitment are more like singlehood for men and LT relationships for women-in terms of T. We were also able to demonstrate what factors mediate the association between partnering and T: in women, frequency of partnered sexual activity mediated the effect in men, interest in more/new partners mediated the effect. This supported our prediction of relationship status interpretations in women, but relationship orientation in men. Results replicated past findings that neither sexual desire nor extrapair sexuality underlie the T-partnering link. We were able to rule out a large number of viable alternative explanations ranging from the lifestyle (e.g., sleep) to the social (e.g., social support). Our data thus demonstrate pattern and mediators for the development of T-pair bonding associations, and emphasize the importance of neither under- nor overstating the importance of gender/sex in research about the evolution of intimacy., (Copyright © 2010 Elsevier Inc.
