Previous studies suggest there is a complex relationship between sexual and general affective stimulus processing, which varies across individuals and situations. We examined whether sexual and general affective processing can be distinguished at the brain level. In addition, we explored to what degree possible distinctions are generalizable across individuals and different types of sexual stimuli, and whether they are limited to the engagement of lower-level processes, such as the detection of visual features. Data on sexual images, nonsexual positive and negative images, and neutral images from Wehrum et al. (2013) (N = 100) were reanalyzed using multivariate support vector machine models to create the brain activation-based sexual image classifier (BASIC) model. This model was tested for sensitivity, specificity, and generalizability in cross-validation (N = 100) and an independent test cohort (N = 18; Kragel et al. 2019). The BASIC model showed highly accurate performance (94-100%) in classifying sexual versus neutral or nonsexual affective images in both datasets with forced choice tests. Virtual lesions and tests of individual large-scale networks (e.g., visual or attention networks) show that individual networks are neither necessary nor sufficient to classify sexual versus nonsexual stimulus processing. Thus, responses to sexual images are distributed across brain systems. ispartof: CEREBRAL CORTEX vol:32 issue:14 pages:3014-3030 ispartof: location:United States status: published

Although researchers are increasingly paying attention to the dyadic nature of sexual desire and its relevance to sexual and relational outcomes, our understanding of how sexual desire operates on a couple level and how it may influence the occurrence of sexual activity in relationships remains limited. This study used ecological momentary assessments to explore to what extent similarity in levels of desire for sex with one's sexual partner, or dyadic sexual desire, was associated with sexual initiations, receptivity to one's partner's initiations, and partnered sexual activity, and how these associations were moderated by perceived partner support. Ninety-four cohabitating couples (M age = 26.30, SD = 7.60) provided six reports a day for 10 consecutive days. We used response surface analysis to examine the associations among both the degree and direction of (dis)similarity in partners' dyadic desire and each of the three outcome variables. Our results revealed that although partners tended to experience similar levels of desire on a moment-to-moment basis, similarity in desire levels was not associated with the three outcome variables. Rather, higher desire within couples predicted each partner's behavioral outcomes. At lower levels of perceived partner support, dyadic sexual desire was negatively associated with women's receptivity to sexual initiations by their partners, indicating high context-sensitivity of women's sexual responding. These findings offer new insights into the links between the similarity in partners' levels of dyadic desire and sexual behaviors in couples, suggesting the need for increased focus on maintaining desire and promoting perceived partner support in clinical practice. ispartof: JOURNAL OF SEX RESEARCH ispartof: location:United States status: Published online

Objective: various sources of evidence suggest that men and women differ in their experience of sexual pleasure. Such gender differences have been attributed to men’s higher innate sex drive, supported by evolutionary psychology perspectives and gender differences in reproductive strategies.Method: this paper presents biopsychosocial evidence for gender similarities in the capacity to experience pleasure, and for substantial gender differences in opportunities for sexual pleasure.Results: we conclude that sexual activity, in most cultures, is less pleasurable and associated with greater cost for heterosexual women than for heterosexual men, even though they do not differ in the capacity for sexual pleasure.Conclusion: since gender differences in experienced sexual pleasure are not a biological given, a more critical discourse of sexual pleasure might create awareness of current inequalities, help lift restrictions for women’s opportunities for pleasure, and could reduce gender differences in the cost of sex. That would truly serve sexual justice around the globe.

Objective: Risk of sexual reoffending of adult men who committed sexual offenses can be understood as involving a network of causally connected dynamic risk factors. This study examined to what degree findings from previous network analyses, estimated using data from the Dynamic Supervision Project (N = 803; van den Berg et al., 2020), could be replicated. Method: Networks produced with data from the provincial corrections system of British Columbia (N = 4,511) were compared with those found in the original sample, using the Network Comparison Test (van Borkulo et al., 2019) and by correlating both the adjacency matrices of the networks and the rank of the node’s strength centrality across networks. Results: Networks without recidivism, with sexual recidivism, and with violent recidivism (including sexual contact) statistically significant differ in network structure, but not in global strength. Both the adjacency matrices of the networks as well as the rank of the node’s strength centrality across networks were highly correlated. Dynamic risk factors general social rejection/loneliness, lack of concern for others, poor cognitive problem-solving, and impulsive acts showed high-strength centralities. Besides, all networks contained distinct communities of risk factors related to sexual self-regulation, emotionally intimate relationships, antisocial traits, and self-management. Conclusions: We successfully replicated most findings of our original study. Dynamic risk factors concerning social rejection/loneliness, cognitive problem-solving skills, impulsive behavior, and callousness appear to have a relatively strong role in the risk of sexual reoffending. Risk management and treatment strategies to reduce recidivism would benefit from a stronger focus on these dynamic risk factors.

This study addressed three goals related to better understanding the factors that contribute to female sexual satisfaction: (a) exploring differences in factors that contribute to perceptions of sexual satisfaction among women with varying sexual identities, (b) evaluating an existing measure of sexual satisfaction among women with diverse sexual identities, and (c) developing potential items for a future expanded measure of the factors contributing to sexual satisfaction. Participants were 996 heterosexual women, 333 bisexual women, and 204 lesbians. They completed an online survey that included a demographic questionnaire, an item measuring sexual satisfaction, an open-ended question about factors contributing to sexual satisfaction, the newly-developed Potential Sexual Satisfaction Factors, and the New Sexual Satisfaction Scale (NSSS). A multinomial regression, an internal consistency analysis, and qualitative analyses were performed to examine the three research questions. Several important differences in factors related to sexual satisfaction were found as a function of sexual identity. In particular, several of the factors that contributed to bisexual women's sexual satisfaction were different than those that contributed to heterosexual and lesbian women's satisfaction. These findings point to the importance of considering sexual identity when researching sexual satisfaction and when providing interventions to improve sexual satisfaction. ispartof: JOURNAL OF SEX RESEARCH vol:58 issue:2 pages:195-205 ispartof: location:United States status: published

Background A number of studies have found that hypersexuality is associated with a high propensity for sexual excitation. In comparison, less is known about the relationship between hypersexuality and sexual arousal at the state level. Also, previous research has revealed a relationship between hypersexuality and negative mood. However, the possibility that sexual response might not be as negatively impacted by negative mood in hypersexual individuals has, as yet, not been tested. Aim The purpose of this study was to investigate sexual responsivity and the effects of negative mood on sexual arousal in hypersexual men who have sex with men (MSM). Methods A total of 211 MSM were assigned to a hypersexuality (N = 81) or a control (N = 130) group using an interview patterned with a semi-structured Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders format. Participants filled out questionnaires and were shown neutral, sexual, and anxiety- and sadness-inducing films. Outcomes Changes in penile circumference and self-reported sexual arousal were the primary outcomes analyzed in this study. Results Controlling for age and HIV status, no differences were found in genital response between hypersexual and non-hypersexual men. Also, the 2 groups did not differ in subjective sexual arousal. Moreover, no effects of negative mood were found. Time series clustering analyses revealed 3 groups—low responders and slow and fast high responders. Sexual excitation, but not sexual compulsivity or pornography use, predicted cluster membership. Clinical Translation Hypersexual MSM may benefit more from an exploration of motivational and behavioral, as compared to psychophysiological, mechanisms underlying possible links between (negative) mood and sexual behavior. Strengths & Limitations Strengths of the study include its sample size, making it one of the larger psychophysiological sex studies; the use of clinical interviews for group assignment; the inclusion of genital response measures; and the application of time series clustering to examine differences among participants. Limitations include possible sample heterogeneity and the reliance on researcher-selected stimuli. Conclusion Given the lack of any effects of negative mood on sexual response in hypersexual MSM, future studies could explore in more depth possible motivational and behavioral effects, including, for example, the impact of negative mood on the tendency to seek out sex as a form of distraction or for validation or emotional support.

Extant literature supports a relationship between sexual arousal and increased likelihood of sexually coercive behavior in men. The present study investigated the impact of sexual arousal on sexual coercion proclivity and the degree to which emotion regulation moderated this relationship in the context of two separate affect inductions. We predicted that sexual arousal would more strongly predict sexual coercion likelihood for men scoring lower on emotion regulation ability compared with men with above average emotion regulation abilities. Male participants with (n = 38) and without (n = 40) self-reported histories of sexual coercion were recruited from urban sexually transmitted infection testing clinics. Participants completed a measure of emotion regulation, underwent a positive and negative affect induction, viewed an erotic video, and reported on their level of sexual arousal immediately prior to completing a hypothetical sexual coercion likelihood laboratory task. Relationships between emotion regulation, sexual arousal, and sexual coercion likelihood were examined using moderation analyses. Sexual arousal was associated with greater reported sexual coercion likelihood. For men with poorer emotion regulation, sexual arousal significantly and positively predicted sexual coercion likelihood in the positive affect condition. Sexual arousal did not significantly predict sexual coercion for men with above average emotion regulation. Findings may have implications for the assessment of individual risk for coercive sexual behavior as well as primary prevention efforts. ispartof: JOURNAL OF INTERPERSONAL VIOLENCE vol:37 issue:1-2 pages:NP264-NP280 ispartof: location:United States status: published

To investigate sexual excitation (SE) and sexual inhibition (SI) profiles in men with erectile dysfunction (ED) and to examine how these dimensions discriminate between men with and without ED.A clinical sample of 37 men with situational (psychogenic) ED and a control group of 40 sexually healthy men (matching the clinical group in age, marital status, and educational level) were constituted. Participants completed self-reported questionnaires assessing sexual function and the propensity for SI and SE.Higher propensities for SI due to the threat of performance failure (SIS1, P.001) and SI due to the threat of performance consequences (SIS2, P.01) were found in the group of men with ED. No significant differences were found between the 2 groups in the propensity for SE.Findings offer additional support for the Dual Control Model of Sexual Response and underscore the relevance of inhibitory mechanisms as potential psychobiological risk factors for the development and maintenance of ED. Findings also highlight the importance of a multidisciplinary approach in the clinical management of ED.

The predominant approach to understand dynamic risk factors of sexual reoffending has been referred to as the Propensities Model (Thornton, 2016). According to this model, dynamic risk factors can be conceptualized as latent constructs whose change alters the risk of sexual reoffending. Despite its strengths and contributions to research, this model does not offer answers to the question of how dynamic risk factors contribute to the risk of sexual reoffending, or of how sustained change in risk might take place. In this paper we introduce the Network-Based Model of Risk of Sexual Reoffending (NBM-RSR), which addresses several limitations and constraints of the Propensities Model and offers empirically testable propositions regarding the nature and development of the risk of sexual reoffending. The NBM-RSR considers risk of sexual reoffending to involve a self-sustaining network of causally connected dynamic risk factors. Consistent with this, an increased risk of sexual reoffending is characterized through a network that contains more and stronger interconnected dynamic risk factors with a higher strength. Sustained change in risk of sexual reoffending occurs when activity in the network exceeds a critical point resulting in a new self-sustaining network. Propositions based on the NBM-RSR are introduced and translated into testable hypotheses. These propositions revolve around (a) risk of sexual reoffending resulting from the construction of a network of causally connected dynamic risk factors, (b) network stability, sudden changes, and critical transitions, and (c) dynamic risk factors’ relative influence on risk of sexual reoffending.

Several studies highlighted the role of insula on several functions and in sexual behavior. This exploratory study examines the relationships among genital responses, brain responses, and eye movements, to disentangle the role played by the anterior and posterior insula during different stages of male sexual response and during visual attention to sexual stimuli. In 19 healthy men, fMRI, eye movement, and penile tumescence data were collected during a visual sexual stimulation task. After a whole-brain analysis comparing neutral and sexual clips and confirming a role for the bilateral insulae, we selected two bilateral seed regions in anterior and posterior insula for functional connectivity analysis. Single-ROI-GLMs were run for the FC target regions. Single-ROI-GLMs were performed based on areas to which participants fixate: "Faces", "Genitals," and "Background" with the contrast "Genitals > Faces". Single-ROI-GLMs with baseline, onset, and sustained PT response for the sexual clips were performed. We found stronger effects for the posterior than the anterior insula. In the target regions of the posterior insula, we found three different pathways: the first involved in visual attention, onset of erection, and sustained erection; the second involved only in the onset of erection, and the third limited to sustained erection. ispartof: SCIENTIFIC REPORTS vol:10 issue:1 ispartof: location:England status: published

The quality of communication between romantic partners has consistently been found to be associated with relationship well-being and stability. Studies on sexual and nonsexual communication, however, have typically assessed communication skills and behaviors using self-report measures. The use of observational methods has several advantages, including the ability to capture and allow for the independent coding of both partners' communication behaviors. With few exceptions, research applying observational methods has not distinguished between sexual and nonsexual communication behaviors. In the present study, we asked 126 young, mixed-sex couples to engage in sexual and nonsexual conflict discussions. The two 7-min discussions were videotaped and rated by trained coders on nine behavioral dimensions using an adaptation of the specific affect coding system (GottmanKrokoff, 1989) and the system for coding interactions and family functioning (LindahlMalik, 2001). Coder ratings applied to the discussion as a whole. Analyses included factor analysis on the behavioral dimensions and multilevel modeling incorporating the actor-partner interdependence model (APIM). We found significant differences in how couples interacted during the two discussions, with more positive (affectionate and validating) and less negative behaviors during sexual discussions as compared to nonsexual discussions. In both women and men, expressions of positivity during the two types of conflict discussions were associated with higher relationship satisfaction. Gender differences were found in the association between negative behaviors during sexual discussions and relationship satisfaction, with men but not women's negative behaviors being associated with lower relationship satisfaction. These findings point at distinct qualities of sexual communication and its association with couples' relational well-being and contribute to a better scientific understanding, with clinical relevance, of sexual and nonsexual communication.

While the interactive nature of sexual desire in women is increasingly recognized, dyadic factors affecting it, including partner interactions, have as yet received little research attention. In this cross-sectional study, we examined the associations among intimacy, celebrated otherness, and object-of-desire affirmation and explored how they complement each other in the prediction of sexual desire in women. Based on the reports of 662 participants, positive correlations were found among all factors. However, in a multiple regression analysis, object-of-desire affirmation emerged as the only positive predictor of sexual desire. ispartof: JOURNAL OF SEX & MARITAL THERAPY vol:45 issue:5 pages:414-423 ispartof: location:England status: published

Sexual health research tends to focus on problematic aspects of sexuality. This also applies to research on sexuality in older men and women, where attention has been primarily on the negative impact of aging. To contribute to the emerging interest in positive (successful) sexual aging, we aimed to: (1) further validate a recently developed 5-dimensional measure of sexual well-being (Štulhofer et al. in J Happiness Stud, 2018. 10.1007/s10902-018-0049-1) and (2) explore the structure of associations among emotional intimacy, frequency of sexual intercourse, and sexual well-being in older European couples. Using data from a 2016 community-based survey of 218 Norwegian, 207 Danish, 135 Belgian, and 117 Portuguese couples aged 60-75 years, we applied actor-partner interdependence structural modeling approach to confirm the validity of the sexual well-being measure in couples and explore a path analytic model in which the frequency of sexual intercourse was hypothesized to mediate the association between emotional intimacy and sexual well-being. Although we observed consistent and significant actor effects, with emotional intimacy and frequency of sexual intercourse predicting both male and female partners' sexual well-being across countries, the proposed mediation was observed only in Norwegian and Portuguese men and Norwegian and Belgian women. Partner effects were gender-specific; male partner's emotional intimacy was related to his female partner's reported frequency of sex and sexual well-being but not the other way around. Apart from being one of the few cross-cultural assessments of successful sexual aging, this study's findings support the use of a new sexual well-being measure in research on older adults' sexuality.
