Sex differences in short-term mating behaviors are well-documented in human sexuality research. Existing studies usually explain sex differences in sexual behaviors through differences in mating preferences, which is theoretically problematic. Using an agent-based model, we investigated the circumstances under which males' and females' differential preferences for short-term mating would result in sex differences in short-term mating behaviors. The model showed that when all individuals in a closed heterosexual population were considered, males and females had the same average number of short-term mating experiences and short-term mates even when males had stronger preferences for short-term mating. Males (vs. females) had a higher average number of both experiences and mates when analyses were limited to only heterosexual males and females who successfully participated in the mating pool (i.e., those with a non-zero number of short-term mating experiences). Moreover, when males (vs. females) had stronger preferences for short-term mating, gay males had a higher average number of experiences and mates compared to both lesbian females and heterosexual males. These results suggest that even when sex differences in mating preferences exist, the sex differences in short-term mating behaviors only occur among particular populations, or when males' preferences for short-term mating are not constrained by those of females. Suggestions for future research in human mating psychology and behaviors were provided.

Through two experimental studies (N = 150), we investigated proxemic behaviors featuring gay/straight dyadic interactions. In doing so, for the first time, we relied on an IR depth camera and considered the interpersonal volume between the interactants, a novel feature that exhaustively captures interactants' proxemic behaviors. Study 1 revealed that the straight participants' implicit sexual bias - but not the explicit prejudice - significantly predicted their volume while interacting with a study accomplice who was presented as gay (vs. straight). However, unlike previous research, mixed-model analyses revealed the higher their implicit bias was, the smaller the interpersonal volume that they maintained with the gay study accomplice, especially when the conversation focused on an intergroup-related (vs. neutral) topic. Study 2 was mainly designed to deepen this main finding. Results documented that highly implicitly biased participants who maintained a smaller interpersonal volume with a gay (vs. straight) study accomplice were more cognitively depleted after the interaction than low-biased participants, possibly suggesting that highly implicitly biased straight people can control this nonverbal behavior to appear as nonprejudiced in the gay interactant's eyes. Implications for research on sexual prejudice and intergroup nonverbal behaviors are discussed.

The Sexual Experiences Survey-Victimization (SES-V; see Koss et al., 2024) revises the prior 2007 Sexual Experiences Survey-Short Form Victimization (SES-SFV) in many ways, including expanded measurement of verbally pressured and illegal sexual exploitation, as well as the addition of items that assess being made to perform a sexual act or to penetrate another person sexually. The current article describes two initial validity studies of the SES-V. Study 1 compared rates of self-reported verbal pressure and illegal sexual exploitation (e.g. rape) on a preliminary version of the SES-V and the SES-SFV in a sample of higher education students who completed both questionnaires online in a randomized order (N = 460). As expected, the preliminary SES-V produced higher rates than the SES-SFV, and continuous scores were strongly correlated. Responses to the made-to-penetrate (MTP) items suggested that some cisgender men and women may have misunderstood those items. Study 2 explored responses to the MTP items further by randomly assigning participants to complete items with either the Study 1 MTP language (n = 269) or revised language (n = 245). The revised language produced fewer implausible responses and was adopted in the final version of the SES-V. These findings provide initial support for the validity of the SES-V and the value of expanding the conceptualization of victimization to include a wider range of sexual exploitation. A research agenda for future validity research is suggested.

The new Sexual Experiences Survey-Victimization (SES-V) was designed to capture a larger range of sexual exploitation and to be applicable to more diverse populations than prior measures. This study represents the first administration of the SES-V in a national sample of adults (N = 347). Participants were recruited from a crowdsourcing platform and selected to reflect the national distribution in terms of age, sex, and race/ethnicity. Rates of sexual exploitation since age 14 were very high in this sample (90%), providing evidence that the SES-V was successful in capturing experiences on the low end of the severity continuum. Using the items corresponding to the FBI definition of rape, 60% of women and 29% of men endorsed rape on the SES-V. Compared to men, women reported higher rates of sexual exploitation overall, and higher rates of every type of sexual exploitation except technology-facilitated. The new SES-V also asks participants to estimate the number of separate instances of four types of sexual exploitation that they have experienced; results provided support for the value of these incident estimates in understanding the scope of sexual exploitation. Finally, this study evaluated new sexual acts and exploitative tactics that were added to the SES-V and found that they demonstrated utility and validity. These findings offer preliminary support for the validity and functionality of the SES-V, although the high prevalence of sexual exploitation on the SES-V is discussed as both a strength and limitation. Future research should evaluate prevalence and demographic differences in a larger national sample.

Sexual Violence (SV) is a public health problem with serious long-term consequences for victims. This scoping review aimed at summarizing the implementation, methodology, characteristics, and efficacy of SV prevention programs conducted in school and community settings with middle and high school students. This study also gathered recommendations for future research. Studies were searched in three databases: EBSCOHOST, SCOPUS and Web of Science. Eighty-six peer-reviewed empirical studies about SV prevention programs applied in school and community settings with samples of middle and high school students were analyzed. Most original studies (46.3%) used sexual violence outcomes, although many approached sexual violence in the context of dating violence (43.3%). Most SV prevention programs were applied in the U.S.A. although studies were identified across the globe. Prevention programs tend to reduce SV attitudes, perpetration, and victimization and to increase SV knowledge, as well as bystander attitudes and behaviors. The evidence reveals the efficacy of these programs, although future studies are needed to clarify the specificities of SV prevention. This article provides recommendations considering the measurement of SV outcomes, the role of technology, the involvement of adults and communities, the timing of interventions, sexual education, and reporting practices.

Attitudes among couples about women's solo masturbation are not well understood. The primary aim of this study was to assess (dis)similarities in attitudes between partners about women's solo masturbation and associations of each partner's attitudes with women's and their partners' sexual satisfaction. One hundred and four mixed-sex couples (M = 27.43 years), recruited through social networking websites and Prolific (an online research participant platform), completed an online survey about demographics, their experiences of solo masturbation, and validated measures of attitudes about women's masturbation and sexual satisfaction. Dyadic data were analyzed using correlational methods and the Actor-Partner Interdependence Model. Women and their partners reported similar and positive attitudes about women's solo masturbation. For women, reports of positive attitudes toward women's solo masturbation were associated with both their own and their partner's sexual satisfaction; there were no associations for men. The role of solo masturbation within romantic relationships is complex but our results support the idea that women's masturbation is now less stigmatized than commonly thought. Normalizing and including masturbation in the sexual script for individuals in relationships may help maximize their, and their partners,' sexual satisfaction.

Exchanging sex for financial compensation is thought to be underreported primarily because extant studies (1) use a single item to capture a complex, stigmatized phenomenon, and (2) do not capture the complex types or reasons why people engage in the sex trades. Few survey studies have explored the sex trades among university students. This study evaluated the psychometric properties of a newly developed measure, the Sexual Services Acts and Materials for Pay (SSAMP), among university students. Surveys were administered to undergraduate (N = 544, time 1; N = 362, time 2) and graduate (N = 331, time 1; N = 187, time 2) students two weeks apart at a predominantly White, public, Midwestern university. Findings suggested that our index had (1) strong convergent validity with the single item used in prior studies, (2) identified more cases of sex trading than the single item, (3) good internal consistency reliability (4) moderate to strong test-retest reliability, and (5) strong discriminant validity. Exploratory factor analysis revealed that items loaded above .59 on a single factor. To our knowledge, this study is the first to evaluate a multi-item sex trades measure in the U.S. Future research should continue to advance the SSAMP and adapt this index to provide credible estimates and nuanced understanding of the sex trades across contexts.

Coerced condomless sex is a prevalent form of sexual coercion that is associated with severe negative health consequences. This scoping review addresses the current lack of synthesized qualitative evidence on coerced condomless sex. Our systematic literature search yielded 21 articles that met review eligibility criteria. Themes of coerced condomless sex were organized into three categories (tactics, motives, and sequelae) and presented separately for studies based on whether researchers stipulated pregnancy promotion intent as underlying the behavior. Coerced condomless sex perpetration tactics ranged from verbal pressure to physical assault. Besides pregnancy promotion, perpetration motives included control, dominance, entrapment, enhancing sexual experiences, and avoiding conflict. Following coerced condomless sex, victims reported developing protective strategies. They also reported experiencing various negative emotional, relational, and physical health effects. Interventions that specifically address coerced condomless sex perpetration and provide supportive programs for those who have experienced coercive condomless sex may be beneficial.
