Factors predicting the probability of initiating sexual intercourse by context and sex

Despite men initiating sex more than women there is considerable variance within the sexes. This study is the first to consider the impact of multiple predictors from the literature, and investigates how factors, such as relationship length, sociosexuality, and different aspects of self‐perceived mate value among others, independently and interactively predict initiation of sexual intercourse in both short‐term sexual and long‐term romantic mating contexts, testing predictions from Sexual strategies theory. For long‐term relationships, positive partner bond increased initiative to sexual intercourse for women. For men, self‐perceived independence increased probability of taking the initiative, while relationship attachment decreased probability. For short‐term relations, the desire component of the sociosexual orientation inventory increased probability of initiation for both sexes, while male initiative was increased by pleasure reasons for sex. The impact of individual predictors on initiating intercourse is influenced by being included in a multidimensional model, and relationship context affects the impact of the predictors.     

Individual differences in preference for risky behaviors during courtship

Engaging in risky behaviors is a sexual signalling strategy that men use to procure mates. The present study investigates men’s preferences for engaging in risky behaviors (along with women’s preferences for their male partner’s risky behavior) within dating couples. We investigated associations between relationship length, self-perceived attractiveness, sociosexuality orientation, and preference for risky behaviors in a sample of 256 couples. Results indicated that men had stronger preferences for risky behaviors than their partner’s ideal preference. Furthermore, relationship length was associated with a decline in women’s preference for their partner’s risk-taking, but not men’s preference for their own risk-taking. Self-perceived attractiveness was negatively associated with risk preference, and sociosexuality orientation was not directly related to risk preference. Female preferences for less intense male risky behaviors could reflect the need of paternal investment which is required for offspring care. Decreased male sexual signalling could account for lower preferences of risky behaviors in females who are involved in longer lasting romantic relationships.     

Men's sociosexuality is sensitive to changes in mate availability

Correlational research has linked mate availability to human sexual behavior, whereby unrestricted sociosexuality seems to be most common under conditions of female abundance. In this study, 71 heterosexual men were randomly assigned to one of two mate availability priming conditions, mate scarcity or mate abundance, and subsequently completed measures of sociosexuality as well as infidelity intentions. Results indicated that men in the mate abundance condition reported stronger sociosexual attitudes and desires, and among those currently in relationships, stronger infidelity intentions. These findings were contrasted with those from a separate sample of 66 heterosexual undergraduate women. Mate scarcity had no effects on women's sociosexuality or infidelity intentions. Findings suggest that when mates are scarce, men will adopt a sociosexual orientation aimed at maintaining a single partner.     

The sexual overperception bias is associated with sociosexuality

As reproductive rates have the potential to be higher in men than women, it is more costly (from an evolutionary perspective) for men to miss a mating opportunity than women. This asymmetry in costs has been proposed to result in men being more sensitive to cues to sexual opportunity than women, and thus men are more likely than women to misperceive sexual interest from opposite sex others. To investigate this sexual misperception bias, smiling male and female faces were presented to participants who were asked to judge whether the face appeared friendly or flirtatious. Participants also completed a sociosexual orientation questionnaire in order to assess their current attitudes towards sexual relationships. In general, we found that males perceive female faces as flirtatious significantly more often than females. However, our results also suggested that people with high scores on the sociosexuality inventory (who rated themselves as more likely to engage in short-term, casual relationships), regardless of sex, had a tendency to perceive the faces of potential mates as more flirtatious, and that this variable explained more variance than sex alone. Our findings demonstrate that sociosexuality may mediate biases in perceiving the sexual intent of others.     

Sociosexuality and everyday social interaction

This study examined whether sociosexuality, a variable measuring unrestrictedness of sexual attitudes and behaviors, relates to the everyday social interactions of individuals. Sociosexuality was measured using Simpson and Gangestad's (1991a) Sociosexual Orientation Inventory (SOI). Seventy-one participants completed daily interaction records assessing various aspects of each interaction they had over a 7-day period. The number of interactions in which they engaged, as well as the number of partners with whom they interacted, were correlated with scores on the SOL In addition, a multilevel data analytic approach was used to examine whether sociosexuality related to perceived Closeness, Quality, Negativity, and Sexual Interest during these interactions. Results were somewhat mixed. Women higher in sociosexuality reported both more extensive social networks and greater numbers of interactions, particularly with men, than women lower in sociosexuality. A marginally significant trend indicated that individuals higher in sociosexuality reported that interactions with their romantic partners contained greater Negativity than individuals lower in sociosexuality. In addition, both men and women higher in sociosexuality reported that interactions with their best friends were of poorer quality.     

Gender differences in beliefs about the causes of male and female sexual desire

Little is known about the beliefs men and women have about the causes of sexual desire, despite the interpersonal and individual significance of those beliefs. Participants in this study received a definition of sexual desire and answered a set of free-response questions exploring their beliefs about the causal antecedents of male and female sexual desire. The results indicated that more women than men view female (and male) sexual desire as caused by external factors. In addition, both men and women believe that male and female sexual desire have different causes: intraindividual and erotic environmental factors are believed to cause male sexual desire, but interpersonal and romantic environmental factors are believed to cause female sexual desire. Although both men and women view physical attractiveness and overall personality as sexually desirable male and female characteristics, women, but not men, view femininity as a sexually desirable female characteristic, and men, but not women, view social and financial power or status as a sexually desirable male attribute.     

Sociosexual Orientation and Sexual Behavior in Mexican Adults

Sociosexual orientation includes individual differences in sexual attitudes and behaviors, in relation to the extent in which an individual could be sexually active without affective bonds and commitment. Sociosexuality is related to sexual behavior and can speak to the differences between men and women in how they express their sexuality ( Simpson & Gangestad, 1991 ; Hebl & Casi, 1995 ; Ostovich & Sabini, 2004 ). This study explores sociosexual orientation and sexual behavior in Mexican adults, in order to identify differences in sociosexual orientation related to biological sex and relationship status. It also assesses the relationship between sociosexual orientation and sexual behavior and to predict sexual behavior from sociosexual orientation. The sample was composed of 209 Mexican adults between 19 and 61 years of age. Thirty‐seven percent were male, and 63% were female. Participants answered a standardized Spanish version of the Sociosexual Orientation Inventory ( Simpson & Gangestad, 1991 ) and a Sexual Behavior Inventory developed for the present project ( García Rodríguez, 2007 ). In general, there is great variability in the frequency of each of the sexual behaviors assessed and in the total number of sexual partners. Moreover, participants perceive themselves restricted in their sexual attitudes and behaviors. Men are more permissive and less restricted in attitudes and behaviors than women, and individuals who are dating informally have a higher behavioral sociosexual orientation than those who are living with their partner. Additionally, the higher sociosexuality, the more frequent sexual practices are and the higher the number of sexual partners. Finally, sociosexuality predicts the frequency of sexual practices and the number of lifetime sexual partners.     

Nonverbal Behaviors and Perceptions of Sexual Intentions: Effects of Sexual Connotativeness,Verbal response,and Rape Outcome

Through the exchange of nonverbal and verbal behaviors, a man and a woman on a date negotiate situated identities. However, a woman's nonverbal and verbal behaviors may reflect an identity discrepant from the one she intended to project, leading to miscommunication between men and women regarding the woman's desire for sexual activity. In Experiment 1, subjects read scenarios in which a woman, Mary, engaged in behaviors that were low, moderate, or high in the degree to which they connotated a desire for sex. In addition, they learned that Mary responded to her date's sexual advances either by saying "no," or by slapping him, or they received no information regarding Mary's verbal response. Subjects were also informed that Mary's date either did or did not force her to have sexual intercourse. Subjects perceived Mary more sexually as her behaviors increased in sexual connotation. In addition, they perceived that Mary desired sex more when no information about her verbal response was provided than when she resisted her date's sexual advances. Subjects also rated the woman more negatively when her nonverbal behaviors were incongruent with her responses to her dale's sexual advances. Contrary to previous research, little evidence of victim derogation was obtained. Results from Experiment 2 showed that men and women agreed in their perceptions of a woman whose behaviors connoted a high interest in sex, but that men perceived behaviors low in sexual connotation ore sexually than women. Implications of the data for understanding sexual miscommunication between men and women as well as reactions to rape victims are examined.     

Is aversion to incest psychologically privileged? When sex and sociosexuality do not predict sexual willingness

As human possess powerful incest-avoidance mechanisms (which likely evolved due to the high costs of inbreeding), reactions to incestuous sexual encounters may be psychologically distinct from reactions to non-incestuous (but still non-normative) sexual encounters. Accordingly, variables such as sex and sociosexuality that normally predict openness to sexual encounters in other situations (i.e., men and sociosexually unrestricted people tend to be more sexually willing) may not do so – or do so only weakly – in incestuous situations. In Study 1, sociosexuality predicted negative judgments of non-incestuous (but still normatively proscribed) sexual acts, but not judgments of incestuous sexual acts. In Study 2, sociosexuality predicted negative reactions to imagined sex with biologically unrelated (but still normatively unusual) partners, but not reactions to imagined sex with related partners (this effect was limited to women); also, men reacted less negatively than women to imagined sex with unrelated partners, but men and women reacted equally negatively to imagined sex with related partners (the latter effect was limited to sociosexually restricted men).     

Dark traits: Sometimes hot,and sometimes not? Female preferences for Dark Triad faces depend on sociosexuality and contraceptive use

Although the Dark Triad personality (i.e., Machiavellianism, narcissism, and psychopathy) has been researched widely, only few studies have investigated women's preferences for men who present high and low Dark Triad features. With an on-line two-alternative forced choice questionnaire we investigated the interaction between preferences of 1962 Finnish women for facial stimuli that differed in the intensity of the Dark Triad traits, accounting for mating context, contraceptive use, and sexual openness (sociosexuality). Among non-contraceptive-using women, unrestricted sociosexuality was positively correlated with preference for high narcissistic male faces, whereas in contraceptive-using women, sociosexuality correlated negatively with preference for high Machiavellian male faces. We suggest that i) facial cues to Dark Triad traits are detectable by women, but ii) their effect on the judgments of attractiveness may vary depending on sociosexuality and contraceptive use, and that iii) preference for narcissism follows similar variation trends as masculinity preference, depending on sociosexuality and the use of hormonal contraception.     

Romantic red: red enhances men's attraction to women

In many nonhuman primates, the color red enhances males' attraction to females. In 5 experiments, the authors demonstrate a parallel effect in humans: Red, relative to other achromatic and chromatic colors, leads men to view women as more attractive and more sexually desirable. Men seem unaware of this red effect, and red does not influence women's perceptions of the attractiveness of other women, nor men's perceptions of women's overall likeability, kindness, or intelligence. The findings have clear practical implications for men and women in the mating game and, perhaps, for fashion consultants, product designers, and marketers. Furthermore, the findings document the value of extending research on signal coloration to humans and of considering color as something of a common language, both within and across species.     

Inferring sexual interest from behavioral cues: Effects of gender and sexually relevant attitudes

Research has found that men impute more sexual meaning to others' behavior than do women. However, little research has examined the possibility that men and women share perceptions of the sexual connotativeness of certain behaviors but diverge in their perceptions of other behaviors. In Study 1, 162 male and 186 female undergraduates, predominantly Caucasian, rated the degree to which each of 27 behaviors of male and female targets connoted a desire for sexual intercourse. Multivariate analyses of variance revealed that, whereas men perceived all but two of the female target behaviors more sexually than women, men and women differed in their perceptions of the sexual connotativeness of only about half of the male target behaviors. A factor analysis revealed three factors for both male and female target behaviors, reflecting mundane dating behaviors, romantic behaviors, and sexual behaviors. Relative to women, men perceived only the mundane dating behaviors more sexually, although regression analyses showed these effects to be moderated by subjects' attitudes toward women. Study 2 examined the extent to which sexually relevant attitudes (e.g., sex role stereotyping, adversarial sexual beliefs, and rape myth acceptance) moderate subjects' perceptions of the sexual connotativeness of the behaviors. Men, particularly those who endorsed traditional, sexually relevant attitudes, were more likely than women to impute sexual meaning to the behaviors. The implications of this for dating situations are discussed.The author wishes to thank Mark Leary and two anonymous reviewers for their comments and suggestions on earlier versions of this article.     

Sexual Peak: Socially Shared Cognitions About Desire,Frequency, and Satisfaction in Men and Women

Is a man’s sexual peak earlier than a woman’s? Three studies were conducted to examine (a) whether the perception that men achieve their sexual peak at a younger age than do women is shared across individuals of different ages and sexes, (b) whether sexual peak is defined differently for men and women, and (c) whether differences between definitions contribute to differences in the age at which men and women are perceived to reach sexual peak. Study 1 suggested that participants believed that females reach their sexual peak at an older age than do males. Study 2 indicated that the defining feature of sexual peak for males was sexual desire and for females was sexual satisfaction. Study 3 suggested that predictions of male sexual peak coincided with participants’ predictions of male age of highest desire and frequency, but not satisfaction, and that female sexual peak coincided with participants' predictions of female age of highest satisfaction but not frequency or desire. Discussion focuses on potential reasons for differences between the perception of male and female sexuality, as well as the social and evolutionary importance of each of the dimensions of sexuality for both males and females.     

Exploitative male mating strategies: Personality, mating orientation, and relationship status

Previous research suggests men are sexually attracted to women displaying cues to sexual exploitability. During human evolutionary history, men’s agreeableness, orientation towards casual sex, and relationship status may have been recurrently associated with greater net benefits of pursuing a sexually exploitative strategy. We hypothesized these three individual differences would predict men’s perceptions of women’s sexual exploitability. Seventy-two men viewed photographs of women and rated their sexual exploitability. Men’s agreeableness, sociosexual orientation, and current relationship status interacted to predict their perceptions of women’s sexual exploitability; among unmated men, the combination of low agreeableness and an orientation toward uncommitted sex was associated with higher perceptions of women’s sexual exploitability. This suggests mechanisms motivating sexually exploitative strategies may depend on an interaction between personality characteristics and situational variables.     

Sex as an obligation and interpersonal communication among Norwegian heterosexual couples

This study examines the prevalence of having sex as a means of satisfying one's partner among a random sample of 398 heterosexual couples with non-problematic, mild or manifest reduced sexual desire. Data collection was carried out by questionnaires. Two of three women and one of five men with manifest distressing reduced sexual desire had had obligatory sex. Among women with symptoms of mild reduced sexual desire, there was an association between obligatory sex and lack of acknowledgement of one's sexual needs, as well as a lack of communication with one's partner regarding how to be sexually pleased. In men with manifest reduced sexual desire there was an association between obligatory sex and discussion of one's sexual needs, and sexual fantasies with the partner. Thus, men with desire problems seem to communicate with their partner about their sexuality, whereas women seem not to talk with their partner about their sexual needs.     

Testing Error Management Theory: Exploring the Commitment Skepticism Bias and the Sexual Overperception Bias

Research on error management theory indicates that men tend to overestimate women's sexual interest and women underestimate men's interest in committed relationships ( Haselton & Buss, 2000 ). We test the assumptions of the theory in face‐to‐face, stranger interactions with 111 man‐woman dyads. Support for the theory emerges, but potential boundary conditions are observed. In addition, we find that women's perceptions of men's desire for commitment is related to the women's own self‐reported sexual interest but that the reverse does not hold for men. Finally, we find evidence consistent with the proposition that people project their own level of interest in sex or in a committed relationship onto their interaction partners.     

Attachment style and sexual permissiveness: The moderating role of gender

An individual difference variable that has been found to predict variation in young adults’ sexual attitudes and behaviors is attachment orientation. Although it has been argued that the association between attachment orientation and sexuality may differ for males and females, only a few studies have explored this possibility, and the results have been inconsistent. With data collected from a large sample (N = 4246) of college students at a U.S. Midwestern University, it was examined how men and women with different attachment styles may vary in sociosexuality and attitudes toward casual sex. This study found evidence that among men, and as hypothesized, a dismissive-avoidant attachment orientation was associated with higher scores on Simpson and Gangestad’s (1991) Sociosexual Orientation Inventory (sociosexuality) and on a measure of approval of sex in casual dating relationships. Among women, however, there was no support found for the hypothesis that an anxious-preoccupied attachment style was associated with greater sexual permissiveness or with approval of casual sex. As hypothesized, however, securely attached women had a lower score on sociosexuality than did women with other attachment styles.     

Orgasm Frequency Predicts Desire and Expectation for Orgasm: Assessing the Orgasm Gap within Mixed-Sex Couples

While previous research has established the existence of an orgasm gap between men and women, research exploring this phenomenon within dyadic samples of mixed-sex couples has been limited. The current study aims to investigate the impact of this orgasm disparity on novel sexual outcomes for couples, including desire and expectation for orgasm. We conducted secondary data analyses on a sample of 104 sexually active mixed-sex couples using an online Qualtrics panel (M_age?=?43.9 years; 94.2% heterosexual; 79.3% White). Cisgender men and women within the couple reported on their sexual satisfaction, orgasm frequency, desired orgasm frequency, expectation for how often people should orgasm (“orgasm expectation”), and perceptions of their partner’s orgasm frequency. An orgasm gap emerged, and men significantly underreported the size of the orgasm gap in their relationships. In a dyadic path model, men’s and women’s own orgasm frequency positively predicted their desire and expectation for orgasm. Additionally, women’s orgasm frequency predicted men’s orgasm expectation. This relationship between orgasm frequencies and expectancies may partially explain women’s lower orgasm importance compared to men. A cycle of orgasm inequality within relationships may be perpetuated when women who experience less frequent orgasms lower their desire and expectation for orgasm. Sex educators, activists, and therapists should work to improve entitlement to sexual pleasure and orgasm, particularly for women who wish to increase their orgasm frequency.
