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.     

Activational and organizational effects of estradiol on male behavioral neuroendocrine function

Evidence is reviewed that establishes an essential role for estradiol, synthesized locally via aromatization of testosterone in the adult as well as the developing male nervous system of rats, ferrets, and mice, in both the organization and adult activation of neural circuits that control appetitive as well as consummatory components of masculine sexual behavior. Evidence is also reviewed suggesting that perinatal estradiol biosynthesis and action in the female's nervous system may contribute to the development of female-typical sexual behavior.     

Does the horny man think women want him too? Effects of male sexual arousal on perceptions of female sexual willingness

ABSTRACT

Disputes over acquaintance rape typically center on the issue of whether the alleged victim consented to sex. Disputed sexual encounters often take place when one or both involved parties is sexually aroused, and this arousal might influence the extent to which the parties perceive sexual consent. Two studies tested the effects of men’s sexual arousal on their interpretations of the extent to which 25 hypothetical female behaviors reflected sexual willingness. Arousal was manipulated via written fantasies (Study 1) or exposure to erotic material (Study 2). Manipulated arousal and individual differences in rated arousal were each associated with greater perceptions of female sexual willingness. Manipulated arousal was significant only for single men in Study 2. Findings suggested present-state sexual arousal affects single men’s interpretations of women’s sexual willingness. Men’s sexual arousal might prominently contribute to misunderstandings in sexual communication.     

The interaction of state and trait aspects of self-focused attention affects genital, but not subjective, sexual arousal in sexually functional women

In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed.     

A neutral odor may become a sexual incentive through classical conditioning in male rats

A neutral olfactory stimulus was employed as CS in a series of experiments with a sexually receptive female as UCS and the execution of an intromission as the UCR. Each experimental session lasted until the male ejaculated. The time the experimental subject spent in a zone adjacent to the source of the olfactory stimulus during the 10 s of CS presentation and the latency to enter that area were employed as measures of conditioning. In Experiment 1, the CS was always presented at the same location in the conditioning arena, bordering the site where the female became accessible. Conditioning resulted in a gradual increase in the time spent in the CS zone as well as in a reduction of the latency to enter it. In Experiment 2, the site of presentation of the CS was varied randomly from one side of the conditioning arena to another in order to assure that the subjects indeed associated the CS and not a particular location with access to a female. Again, the time spent in the CS zone increased and the latency to enter it was reduced by conditioning. Furthermore, after conditioning the CS was approached more than a neutral odor in a different context. In a third experiment one group of animals was randomly exposed to the CS to control for non-associative effects on performance. Another group was conditioned as in Experiment 2. The random presentation of the CS failed to enhance approach, while the paired UCS-CS had effects identical to those found in Experiment 2. In the last experiment, an olfactory CS⁻ was included. The CS⁺ and CS⁻ were presented in random order at random locations. Both the time spent in the CS⁺ and CS⁻ zones was increased, while the latency to enter the zone was significantly reduced only for the CS⁺. These data suggest that the subjects had partially learned to discriminate between the CS⁺ and the CS⁻, at most. The procedure employed in Experiments 2 and 3 seems to be the most promising for studies of sexual conditioning in male rats.     

Conditioning of appetitive and consummatory sexual behavior in male Japanese quail.

Two different types of stimulus objects, a live female quail artificially adorned with bright orange feathers and an inanimate toy dog, served as conditioned stimuli. For subjects in experimental groups, the conditioned stimuli were presented shortly before access to a sexually receptive normal female quail. For subjects in control groups, exposure to the conditioned stimuli was unpaired with copulatory opportunity. Subjects in the experimental but not in the control groups quickly came to approach the location of the conditioned stimulus objects. When an adorned female quail served as the conditioned stimulus, the conditioned approach behavior was controlled by a combination of the presence of the orange adornments and the visual cues of the head and neck of the female bird, and the approach behavior persisted as the adorned female moved to new locations. When the toy dog served as the conditioned stimulus, the conditioned approach behavior was limited to the spatial cues that surrounded the toy dog during conditioning trials. Although both types of stimulus objects evoked conditioned approach behavior, only the adorned female stimulus supported copulatory behavior. This last finding indicates that copulatory behavior can become redirected toward novel stimuli as a result of conditioning, but only under special circumstances. The results are consistent with the suggestion that appetitive components of reproductive behavior are more susceptible to conditioning than consummatory components. Possible reasons for this are discussed, together with implications of the results for the contribution of conditioning processes to sexual selection.     

Body appreciation,sexual relationship status,and protective sexual behaviors in women

The relationship between body appreciation and sexual risk reduction behavior in women is under-explored. This cross-sectional study examined the relationships between body appreciation, male condom use, and sexually transmitted infection (STI) testing among a community-based sample of women (n = 285). Logistic regression results revealed that after controlling for age, BMI, and sexual orientation, having more than one sexual partner moderated body appreciation and current male condom use (OR = 4.21, p < .01, CI = 1.510–11.726). Body appreciation was not a significant predictor of STI testing in the previous 12 months. This suggests that women with higher body appreciation may be more likely to engage in some protective sexual health behaviors. Interventions that seek to improve body appreciation instead of body size change such as weight loss or gain may encourage certain protective sexual behaviors in women.     

Self-objectification,body self-consciousness during sexual activities,and sexual satisfaction in college women

Few studies examine the mechanisms that link body image to sexual satisfaction in women. Using the tenets of objectification theory, this study investigated the relationships between body surveillance, body shame, body self-consciousness during sexual activities, and sexual satisfaction in an ethnically diverse sample of American female college students (N = 368), while controlling for relationship status and body mass index. Results based on self-report measures of these constructs suggested that body shame and body self-consciousness during sexual activity were negatively correlated with sexual satisfaction. Additionally, path analysis indicated that body surveillance predicted increased body self-consciousness during sexual activity, partially mediated by body shame. Body self-consciousness, in turn, predicted decreased sexual satisfaction. Overall, study findings highlight the negative consequences of body image concerns for women's sexual satisfaction.     

Functional analysis and treatment of inappropriate sexual behavior

The results of a functional analysis showed that inappropriate sexual behaviors exhibited by a 9-year-old boy who had been diagnosed with traumatic brain injury were maintained by positive reinforcement in the form of social attention. An intervention consisting of functional communication training and extinction resulted in reduced levels of inappropriate sexual behaviors.     

The expression of the genes of aggressiveness in mice: The effect of androgen on aggression and sexual behavior in females

Female mice of strains selectively bred for aggressiveness or nonaggressiveness were injected with testosterone propionate (TF′) at the age of 2 days and as adults, or they were injected as adults only. Aggressive and sexual behavior was then tested with female, receptive female, and male partners before, during, and after the latter TP treatment. The females that had received both TP treatments displayed as much or as little aggression as males of the same strain, leading to the conclusion that aggressiveness genes are not linked with the male sex chromosome, even though they depend on it for their expression. The sexual behavior of the females of both strains that had received both TP treatments was altered to the male type. In the females of the aggressive strain even adult treatment alone was sufficient for this change. Aggressiveness and male sexual behavior would seem to be determined separately, although aggressiveness facilitates the display of male sexual behavior.     

Cognitive and physiological indices of sexual arousal in homosexual,bisexual, and heterosexual males

Cognitive and physiological indices of sexual arousal were investigated utilizing groups of homosexual, bisexual, and heterosexual subjects (ten subjects per group) who were presented both homosexual and heterosexual films and slides. The results indicated that both homosexual and heterosexual subjects were able to estimate accurately their degree of erection to the erotic stimuli. Bisexual subjects, however, showed a large discrepancy between the magnitude of actual erection and verbally reported estimates of penile tumescence. In terms of physiological arousal, the erectile responses of the homosexual and bisexual groups were indistinguishable, a finding which questions the existence of male bisexuality as distinct from homosexuality or as a different sexual orientation in males.     

Workplace fairness and emotional exhaustion in Nigeria police: The moderating role of gender

Abstract

This study examined the moderating role of gender in the relationship between perceived workplace fairness and reported level of emotional exhaustion among a sample of Nigeria police. A total of 214 participants took part in the cross-sectional survey. Results of the moderated hierarchical regression analysis provided support for gender as a moderating variable in the relationship between perceived workplace fairness and emotional exhaustion, such that perceived workplace fairness was a stronger predictor of emotional exhaustion among male police than for female police. The practical implications for the management of emotional exhaustion in general, and for the Nigeria police in particular, were emphasized.     

Effects of low survivability cues and participant sex on physiological and behavioral responses to sexual stimuli

According to life history theory, environmental cues indicating that one's future survivability is low increase reproductive effort. This suggests that exposure to low survivability cues will increase people's preparedness to engage in sex. However, according to sexual selection theory and parental investment theory, evolutionary pressures favored a more conservative sexual strategy among women compared to men. We therefore hypothesized that men, but not women, would respond to low survivability cues with increased sexual preparedness. Accordingly, both subliminal and supraliminal death primes (as compared with control primes) led men, but not women, to exhibit increased physiological arousal in response to sexual images (Study 1), and stronger approach-oriented behavioral responses to sexual images (Study 2). Theoretical implications for life history theory are discussed.     

Church and choices: a qualitative exploration of lived sexual values in young adult women

This qualitative research article discusses three crucial encounters in the sexuality education experiences of young adult women who were raised Catholic by drawing from the analyzed interview data of 15 such women. Using the framework of lived theologies, the author argues that understanding the impact of these encounters helps theological scholars better understand the way that young adults from religious backgrounds make decisions about relationships and sexuality. The young adult women interviewed for this research highlight a defensive posture in sexual decision-making that reflects poor preparation for the realities of relationships and a lack of opportunities to clarify and specify their own sexual values prior to these occasions.     

The relationship between aggressive and sexual behavior in male mice: Effects of testosterone and parachlorophenylalanine

The purpose of this study was to clarify the connection between aggressive and sexual behavior with the aid of testosterone propionate (TP) and parachlorophenylalanine (PCPA). Previous studies have indicated that aggressive and sexual behavior are positively correlated, and it has been suggested that both behaviors are related to the level of general arousal. Testosterone has documented effects on both aggressive and sexual behavior. It has been hypothesized that these effects are due to an increased level of general arousal. If this is the case, aggressive and sexual behavior could be restored by administration of drugs excitating the central nervous system, e.g., PCPA. The present study examined the effects of TP and PCPA on aggressive and sexual behavior in gonadectomized male mice. Control animals were injected with sesame seed oil or saline. The level of aggressiveness was assessed by means of dyadic tests with gonad-intact male opponents. For the sexuality tests, a receptive female was placed in the home cage of the experimental male. The results showed that male mice injected with PCPA were more aggressive than the males of the other groups, while the TP-exposed males expressed the most sexual activity. Compared to the control group, the PCPA and TP groups were more active in both the aggression and the sexuality tests. These findings lend support to the hypothesis that the earlier documented correlations between aggressive and sexual behavior could be due to both behaviors being dependent on a certain level of general activation.

The effects of alcohol intoxication and sexual interest on men's sexual persistence and hostility in a dating simulation

Perpetrators of sexual assault are often intoxicated; however, few experimental studies evaluate alcohol's “in the moment” effects on sexual aggression. This study extends past theory and research by examining the acute effects of alcohol on men's decisions about how to respond to sexual refusals in a dating simulation. Men (N = 62) ages 21–29 were randomly assigned to consume alcohol (target breath alcohol level 0.080%) or no alcohol. Participants were encouraged to talk to a simulated woman and act as they would on an actual date. They made choices from a list which included nonsexual and sexual options. The female agent was programmed to engage in some sexual activities but refuse others. Refusals became more intense if participants persisted. Negative binomial regression analysis was used to test a path analytic model. As predicted, participants' self‐reported desire to have sex was positively associated with choosing more consensual sexual activities during the simulation (i.e., activities in which the woman willingly engaged). Consensual sexual activities were positively associated with the number of times participants persisted after the woman refused. Alcohol moderated this relationship such that it was stronger for intoxicated men than sober men. The more sexual refusals participants received, the more hostile verbal comments they made to the woman. Contrary to our predictions, this relationship was not moderated by alcohol condition. Because participants had multiple opportunities to escalate their aggression or desist, this paradigm provides new insights into the mechanisms through which intoxication enhances the likelihood of sexual aggression in dating situations.
