      Consensual non-monogamy (CNM) is a non-normative relationship that can generally be defined as relationships in which the involved individuals have openly agreed that they can have other sexual and/or affective partners. Despite growing interest in CNM, little research has been conducted regarding characteristics of the involved individuals, as well as comparing CNM individuals and monogamous individuals' characteristics. Expanding this research is important, as CNM constitutes a sizeable minority group, and CNM individuals and relationships are subject to stigma and dehumanization. The present study compared CNM and monogamous individuals in terms of personality (including "dark" personality) and mating orientations (sociosexuality and long-term mating) in young Spanish university students. Main results indicated that CNM individuals did not differ much in personality nor were they prone to higher "dark" personality traits when compared to monogamous individuals. Regarding mating orientations, CNM individuals were prone to higher sociosexuality levels and lower levels of long-term mating. Interestingly, results showed positive correlations between sociosexuality and "dark" personality in monogamous individuals, but not in CNM individuals. In conclusion, young Spanish university CNM individuals seem to be more pro-sex than monogamous people and less committed to the romantic love narrative of long-term mating, but these individuals were not more untrustworthy, self-centered, ruthless, or malevolent. Results were also discussed regarding their implications in the stigma and dehumanization of CNM people.

      Prior research acknowledges that families and peers influence adolescents' sexual behaviors. Far fewer studies have explored whether and how families and peers influence sexual behaviors among emerging adults, especially among those in committed intimate partnerships, while also accounting for dynamics specific to the intimate relationship and respondents' sociodemographic characteristics. Even less is known about whether and how previous romantic relationship experiences might influence emerging adults' future sexual behavior both within and outside the confines of committed intimate partnerships. Drawing on longitudinal data from the Toledo Adolescent Relationships Study, we examined how emerging adults' family backgrounds, peers' sexual attitudes and behaviors, and past and current relationship experiences influenced their engagement in casual sex and sexual non-exclusivity. We found that each of these contexts was significant predictors of emerging adults' casual sex, and that both peers and romantic relationship experiences significantly influenced the likelihood of engaging in sexually non-exclusive behaviors among those in committed dating, cohabiting, and marital partnerships. We discuss potential theoretical mechanisms linking these relationships and provide suggestions for future research.

      We tested the good genes ovulatory shift hypothesis through speed-dating, an ecologically valid paradigm with real life consequences. Fifteen speed-dating sessions of 262 single Asian Americans were held. We analyzed 850 speed-dates involving 132 men and 100 normally ovulating women, finding ovulatory shifts in the desirability of men with more masculine facial measurements (smaller eye-mouth-eye angle, larger lower face to full face height ratio, and smaller facial width to lower face height ratio) in the predicted direction. However, there was no support for ovulatory shifts in preferences for men's self-reported height. In addition, the expected shifts were not found for women's second date offers to men. Therefore, with natural stimuli and in a competitive dating scenario, we partially replicated previously documented ovulatory shifts in women's preferences for men.

       Background and Aims: Marriage has been a functional and moral relationship between men and women, which leads to the creation of a family and also can result in the birth of a child. This study aimed at determining the mate-selection criteria of nursing students.
    Methods: 298 nursing students were considered in this cross-sectional, descriptive-analytical study. The study data were collected using a researcher-made questionnaire with confirmed validity and reliability.
    Results: The male and female undergraduate students' mean age was 20-37 and 20-30 years, and male and female graduate students were aged 22-33 and 23-39 years, respectively. From the girls' perspective, 24 out of the 46 criteria were essential for mate selection. From the boys' perspective, 17 criteria were important and five were very low important. The results revealed a significant difference between both genders regarding the importance of 29 criteria. Boys believed that having housekeeping skills, coming from similar cities, and having physical attractiveness were of utmost importance.
    Conclusion: Girls paid more attention to psychological and economic criteria in comparison with men. For girls, the husband's nobility and ability to manage the family and for men being a housewife were more important. Despite the differences in some points of view between both genders about considering the criteria for choosing a future spouse, according to all participants, it was important for the participants to include psychological, cultural, familial, and social criteria for choosing a mate selection. It is recommended that, before marriage, the youth should consider the above-mentioned criteria to choose their future spouse. In addition, as much as possible, boys should have a decent job and an independent income before marriage.

      Research on men's sexual exploitation of women has documented that men's psychology tracks cues associated with the ease of women's exploitability. In the current studies, we examined a different class of cues hypothesized to aid men's use of sexually exploitative strategies: environmental cues to the likelihood of discovery. We defined likelihood of discovery as the perceived probability of identification when engaging in exploitative behavior (e.g., presence of others). We test the hypothesis that men's likelihood to rape increases when their perception of the likelihood of discovery is low in three studies. In Study 1, we conducted a content analysis of individuals' responses (N = 1,881) when asked what one would do if they could stop time or be invisible. Besides the "other" category whereby there were no specific category for nominated behaviors, the most nominated category included sexually exploitative behavior-representing 15.3% of reported behaviors. Both Studies 2 (N = 672) and 3 (N = 614) were preregistered manipulations of likelihood of discovery surreptitiously testing men's rape likelihood to rape across varying levels of discovery. We found men, compared to women, reported a statistically higher likelihood to rape in both Studies 2 and 3: 48% compared to 39.7% and 19% compared to 6.8%, respectively. Across Studies 2 and 3, we found no statistical effect of the likelihood of discovery on participants' likelihood to rape. We discuss how the presence of one's peers may provide social protection against the costs of using an exploitative sexual strategy if a perpetrator is caught.
