Erectile dysfunction (ED) can have negative consequences for men and their intimate partners. The purpose of the present research was to replicate and extend the results of previous studies concerning the connections that ED has with partner-directed behaviors using a sample of heterosexual romantic couples. Specifically, we used an actor-partner interdependence mediation model to examine whether the associations that ED had with men's mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injuries were mediated by suspicious jealousy, but not reactive jealousy. These associations were examined in 113 romantic couples, using men's self-reports, and partner-reports provided by their female partners. Results indicated that suspicious jealousy (but not reactive jealousy) mediated the associations that ED had with men's use of partner-directed behaviors, such that higher levels of ED were associated with men experiencing more suspicious jealousy, which, in turn, was associated with more cost-inflicting mate retention behaviors, benefit-provisioning mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injury. However, there were some discrepancies between the reports provided by men and women such that these associations emerged more consistently in the partner-reports provided by women than in the self-reports provided by men. Discussion addresses evolutionary implications of these findings, as well as limitations of this research and directions for research concerning ED., (© 2023.

Psychopathic men sometimes direct sexual aggression toward prospective female partners (e.g., using sexually aggressive behavior on a first date) and such behavior may be indicative of a high mating effort strategy. Less research has investigated the role of psychopathy in men's use of sexually coercive behaviors in their intimate relationships (e.g., sexual aggression directed toward one's long-term romantic partner) or the relationship processes that might facilitate such behavior. The present study surveyed 143 heterosexual dyads to assess men's psychopathic traits and their relation to self-reports and partner-reports of men's jealousy and partner sexual coercion. Results across informant models showed that men's psychopathy was associated with higher suspicious jealousy and partner sexual coercion. Suspicious jealousy also indirectly linked men's psychopathic traits with engaging in partner sexual coercion. The findings provide novel insights using dyadic data and suggest that both psychopathy and jealousy are important for men's engagement in partner sexual coercion., (© 2023.

Erectile dysfunction (ED) has been shown to be associated with several negative aspects of intimate relationships. Our goal for the present research was to examine whether ED was associated with men's use of sexual coercion in their intimate relationships (which may include the use of physical coercion, psychological manipulation, or emotional manipulation to gain sexual access) and if perceived sperm competition risk (i.e., perceived risk of partner infidelity, which may place a man's sperm into competition with sperm from another man) played a role in this association. These associations were examined in Study 1 using self-reports provided by men (N = 202) who had a mean age of 30.48 years (SD = 5.03) and were recruited through Amazon's Mechanical Turk (MTurk). ED was found to have a large positive association with sexual coercion. However, men's self-reports did not provide support for sperm competition risk moderating the association between ED and sexual coercion, but an exploratory analysis revealed that sperm competition risk mediated this association. We attempted to replicate and extend these results in Study 2 by using partner-reports provided by women (N = 151) who had a mean age of 30.41 years (SD = 4.77) and were recruited through MTurk. Women's partner-reports provided support for sperm competition risk moderating the association between ED and sexual coercion. In addition, an exploratory analysis found that sperm competition risk also mediated the association between ED and sexual coercion, similar to Study 1. Discussion explores the implications of these results for understanding the role that sperm competition risk may play in the connection between ED and sexual coercion., (© 2022.
