Orgasms during consensual sex are often assumed to be wholly positive experiences. This assumption overshadows the possibility that orgasm experiences during consensual sex could be "bad" (i.e., negative and/or non-positive). In the present study, we employed an online survey to explore the possibility that orgasm experiences could be "bad" during consensual sex by asking participants of diverse gender and sexual identities (N = 726, M age = 28.42 years, SD = 7.85) about a subset of potential bad orgasm experiences. Specifically, we asked participants whether they have ever had an orgasm during coerced sex, compliant sex, and/or when they felt pressured to have an orgasm (i.e., orgasm pressure). We also asked participants who had such an experience to describe it, resulting in qualitative descriptions from 289 participants. Using mixed quantitative and qualitative analyses, we found compelling evidence that orgasm experiences can be "bad" during consensual sex. Specifically, many participants described their experiences in negative and/or non-positive ways despite orgasm occurrence, reported that their orgasms were less pleasurable compared to other experiences, and suggested that their orgasm experiences had negative impacts on their relationships, sexuality, and/or psychological health. Participants also suggested that social location shaped their bad orgasm experiences, citing gender and sexual identity, gender identity conflict, race/ethnicity, and religion as important to their perceptions of and responses to their experiences. Results directly challenge the assumption that orgasms during consensual sex are always and/or unilaterally positive experiences.

Research on feminist identification in men has often focused on men who identify as feminist or who assert agreement with feminist goals. For some men, however, choices surrounding feminist self-identification may be uncertain in ways that are meaningful indicators of their beliefs and values. We hypothesized that men who were uncertain about their feminist identity held beliefs that fell between their feminist and non-feminist peers, representing a unique ideological position. We tested this possibility by comparing feminist, “unsure”, and non-feminist U. S. college (n = 533) and community (n = 277) men’s masculinity stress and conformity, gender role values, and approaches to sexual relationships. Results showed that unsure men’s gender role values fell between feminist and non-feminist men, but unsure men were more like feminists for some components of masculinity and more like non-feminists for others; on some constructs, feminist, unsure, and non-feminist men were similar. For sexual relationships, all men were equally invested in a sexual partner’s pleasure, but unsure men and feminist men were less concerned with receiving sexual favors in exchange compared to non-feminists. We discuss how acknowledgement of men’s uncertainty about their feminist identity may be useful for how researchers assess men’s relationship to feminism, how instructors teach men about feminism in classroom settings, and how activists involve men in the feminist movement.

Sexual desire and testosterone are widely assumed to be directly and positively linked to each other despite the lack of supporting empirical evidence. The literature that does exist is mixed, which may result from a conflation of solitary and dyadic desire, and the exclusion of contextual variables, like stress, known to be relevant. Here, we use the Steroid/Peptide Theory of Social Bonds as a framework for examining how testosterone, solitary and partnered desire, and stress are linked over time. To do so, we collected saliva samples (for testosterone and cortisol) and measured desire as well as other variables via questionnaires over nine monthly sessions in 78 women and 79 men. Linear mixed models showed that testosterone negatively predicted partnered desire in women but not men. Stress moderated associations between testosterone and solitary desire in both women and men, but differently: At lower levels of stress, higher average testosterone corresponded to higher average solitary desire for men, but lower solitary desire on average for women. Similarly, for partnered desire, higher perceived stress predicted lower desire for women, but higher desire for men. We conclude by discussing the ways that these results both counter presumptions about testosterone and desire but fit with the existing literature and theory, and highlight the empirical importance of stress and gender norms.

Women often expect to encounter negative, problematic content when they consume pornography, yet many women use and enjoy pornography anyway. Some research has centered content type (e.g., sexist/violent vs. nonsexist/women-focused) as a key determinant of women's pornography experiences, but this precludes the notion that women are active, engaged consumers of pornography and minimizes women's role in shaping their own experiences. In the present study, we explored how a sample of sexually diverse women in the U.S. (aged 18-64; N = 73) worked toward positive experiences with pornography via active negotiation with negative content, using a secondary analysis of focus group data on women's sexual pleasure. We found that, although women often experienced pornography as risky, many women used it anyway and actively employed strategies to increase the likelihood of having a positive experience. Women's strategies were similar across sexual identity and age groups, but the heteronormative, youth-oriented portrayals of sexuality in mainstream pornography presented unique concerns for heterosexual, queer, and older women. Results have implications for how women can be conceptualized as active, rather than passive, consumers of pornography as well as for how women's agency might influence women's arousal responses to sexually explicit stimuli in research.

Testosterone (T) is implicated in tradeoffs between competition for new partners and nurturance within existing pair bonds. Some evidence suggests women in committed romantic relationships have lower T than singles, similar to findings in men. However, it is unclear whether lower T predicts pair bonding or vice versa, as well as how sexual activity might be implicated in within-person links between T and partnering. We conducted a longitudinal study on T and partnering in women, rooted in the Steroid/Peptide Theory of Social Bonds. Participants (78 women) provided saliva samples for T and completed questionnaires about relationships and sexuality at up to nine monthly study sessions. T and relationship status were bidirectionally linked: lower T predicted becoming committed, and becoming committed then increased women’s T. Masturbation was associated with higher T across relationship statuses; however, dyadic sexual activity moderated T-partnering links, such that committed women only had lower T than singles when they were dyadically sexually active. Results point to reciprocal, interactive associations between partnering, sexuality, and T and generate testable hypotheses for unexpected associations via the S/P Theory.

Sexual desire is increasingly understood to be multifaceted and not solely erotically oriented, but measures are still generally unitary and eroticism-focused. Our goals in this article were to explore the multifaceted nature of sexual desire and develop a measure to do so, and to determine how multifaceted sexual desire might be related to gender/sex and sexual orientation/identity. In the development phase, we generated items to form the 65-item Sexual Desire Questionnaire (DESQ). Next, the DESQ was administered to 609 women, 705 men, and 39 non-binary identified participants. Results showed that the DESQ demonstrated high reliability and validity, and that sexual desire was neither unitary nor entirely erotic, but instead was remarkably multifaceted. We also found that multifaceted sexual desire was in part related to social location variables such as gender/sex and sexual orientation/identity. We propose the DESQ as a measure of multifaceted sexual desire that can be used to compare factor themes, total scores, and scores across individual items in diverse groups that take social context into account. Results are discussed in light of how social location variables should be considered when making generalizations about sexual desire, and how conceptualizations of desire as multifaceted may provide important insights.

Testosterone (T) and pair bonding in men are linked such that lower T is associated with monoamorous partnering (i.e., with one person) and high T is associated with singlehood. However, it has remained unclear whether T levels predict partnering status or vice versa. Evidence suggests time course of T measurements in relation to partnering as well as nurturant and sexual experiences may affect whether T predicts partnering or vice versa and that transitions into or out of partnerhood may have unique associations with changes in T. We examined links between salivary T levels, relationship status, and relationship status transitions in 78-first year male college students over an approximately year-long period. Using longitudinal data, our findings largely support trait associations between T and relationship status in men, i.e., that T predicts relationship status. However, our data also provide novel evidence of dynamic associations and differences in T levels at different relationship status transitions.

Solitary and partnered sexuality are typically depicted as fundamentally similar, but empirical evidence suggests they differ in important ways. We investigated how women's definitions of sexual pleasure overlapped and diverged when considering solitary versus partnered sexuality. Based on an interdisciplinary literature, we explored whether solitary pleasure would be characterized by eroticism (e.g., genital pleasure, orgasm) and partnered pleasure by nurturance (e.g., closeness). Via focus groups with a sexually diverse sample of women aged 18-64 (N = 73), we found that women defined solitary and partnered pleasure in both convergent and divergent ways that supported expectations. Autonomy was central to definitions of solitary pleasure, whereas trust, giving pleasure, and closeness were important elements of partnered pleasure. Both solitary and partnered pleasure involved exploration for self-discovery or for growing a partnered relationship. Definitions of pleasure were largely similar across age and sexual identity; however, relative to queer women, heterosexual women (especially younger heterosexual women) expressed greater ambivalence toward solitary masturbation and partnered orgasm. Results have implications for women's sexual well-being across multiple sexual identities and ages, and for understanding solitary and partnered sexuality as overlapping but distinct constructs.

Sexual orientation typically describes people's sexual attractions or desires based on their sex relative to that of a target. Despite its utility, it has been critiqued in part because it fails to account for non-biological gender-related factors, partnered sexualities unrelated to gender or sex, or potential divergences between love and lust. In this article, I propose Sexual Configurations Theory (SCT) as a testable, empirically grounded framework for understanding diverse partnered sexualities, separate from solitary sexualities. I focus on and provide models of two parameters of partnered sexuality--gender/sex and partner number. SCT also delineates individual gender/sex. I discuss a sexual diversity lens as a way to study the particularities and generalities of diverse sexualities without privileging either. I also discuss how sexual identities, orientations, and statuses that are typically seen as misaligned or aligned are more meaningfully conceptualized as branched or co-incident. I map out some existing identities using SCT and detail its applied implications for health and counseling work. I highlight its importance for sexuality in terms of measurement and social neuroendocrinology, and the ways it may be useful for self-knowledge and feminist and queer empowerment and alliance building. I also make a case that SCT changes existing understandings and conceptualizations of sexuality in constructive and generative ways informed by both biology and culture, and that it is a potential starting point for sexual diversity studies and research.

Jealousy evokes strong psychological responses, but little is known about physiological effects. This study investigated whether actively thinking about a jealousy-provoking situation would result in a testosterone (T) response, and what factors might mediate this effect. We examined T responses to imagining one’s partner engaging in one of three activities: a neutral conversation with a co-worker, a flirtatious conversation with an attractive person, or a passionate kiss with an attractive person. Women in the flirting condition experienced a significantly larger increase in T relative to those in the neutral condition; the kissing condition was intermediate. In men, there were no significant effects of jealousy condition on T. These findings are consistent with the Steroid/Peptide Theory of Social Bonds, such that the flirting condition elicited a ‘competitive’ T response, and the kissing condition elicited responses consistent with defeat.

Testosterone (T) is generally understood to influence sexual behavior, but how T responds to sexuality is less well characterized across vertebrate species. Here, we review and synthesize findings on sexual modulation of T in primates (including humans), birds, fish, and rodents, with attention to the specific elements of sexual situations that drive T responses. We use a comparative perspective to show how research with females and males from a wide distribution of taxa provides novel insights for understanding effects of sexuality on T in humans. Among other patterns, our cross-species synthesis highlights a) the importance of the context surrounding a sexual interaction, over and above specific sensory modalities, to sexual modulation of T; b) that changes in T and changes in sexual behavior or arousal do not always occur in concert; c) that sexual contexts may be especially likely to increase T when coupled with aggression or competition, but sexuality contributes to T profiles independently as well; and d) that variation in T responses may be adaptive in balancing behavioral and physiological costs and benefits of T. We discuss how broadening the ways sexuality is defined, and especially decoupling sexuality from reproduction, would further clarify predictors and potential functions of sexually-modulated T. Overall, effects of sexuality on T across species highlight the malleability of androgens, particularly in response to the social environment. Not only does sexual behavior affect T, but the social environment in turn modulates the extent of sexuality’s effect on T.

Sexual stimuli increase testosterone (T) or cortisol (C) in males of a variety of species, including humans, and just thinking about sex increases T in women. We investigated whether sexual thoughts change T or C in men and whether hormone measures (baseline, post-activity, and changes) correlate with psychological sexual arousal. We used the Imagined Social Situation Exercise to assess how hormones respond to and correlate with sexual thoughts and arousal relative to three control conditions: neutral, stressful, and positive. A total of 99 men provided a baseline saliva sample, imagined and wrote about a sexual or control situation, and provided a second saliva sample 15 min later. Results indicated that, for participants in the sexual condition, higher baseline and post-activity C corresponded to larger increases in self- reported sexual and autonomic arousal. Although sexual thoughts increased sexual arousal, they did not change T or C compared to control conditions. Our results suggest that sexual thoughts are not sufficient to change T or C in men, but C may facilitate sexual arousal by directing energy towards a sexual situation.

Parthenogenetic lineages are predicted to be initially successful, but predisposed to deteriorate due to insufficient genetic diversity. Unexpectedly, parthenogenetic moths do not show any signs of deterioration. We hypothesize that these moths may exhibit levels of genetic diversity which allow them to successfully persist. To test our hypothesis, we assess polymorphism in 11 new isolated microsatellite loci from the parthenogenetic Dahlica fennicella. We also report their variability in another parthenogenetic species D. triquetrella and five sexual related species (Dahlica and Siederia spp). Nine loci in D. fennicella and one in D.triquetrella were found to be polymorphic, whereas five loci showed polymorphism among sexual species. Our results are incongruent with previous cytological observations, which indicate that parthenogenetic reproduction in Lepidoptera has no crossing over. Some plausible explanations for the observed polymorphism include recombination, high mutation rate, and multiple clonal origins.

Athletes who fail are susceptible to negative affect (NA) and impaired future performance. Functional magnetic resonance imaging (fMRI) studies have identified prefrontal, anterior cingulate, and limbic activations following negative mood provocation. Little is known about the neural correlates of negative self-reference (SR), especially in athletes. Even less is known about the neural correlates of the effects of cognitive intervention (CI) in modifying negative SR and NA in this population. In an fMRI study, 13 athletes watched a video of their own career-threatening defeat in two controlled blocks. Between fMRI blocks, they received a 20-min CI designed to assist in event reappraisal and planning for future performance. Relative increases post-CI were seen in pre- motor (BA6) and sensorimotor (BA4/1) cortices. Correlated with mood ratings, relatively higher pre-CI levels were seen in the ventromedial prefrontal cortex, the right dorsomedial prefrontal cortex (PFC; BA10), the right dorsolateral PFC (BA45), the anterior cingulate, and the right parahippocam- pus. CI may counteract the detrimental effects of NA and negative SR on premotor and motor activity.

We investigated the prognostic significance of extracellular matrix metalloproteinase inducer (EMMPRIN) and matrix metalloproteinase 2 (MMP-2) in epithelial ovarian cancer as well as their relation to hyaluronan (HA) expression.The expression of EMMPRIN and MMP-2 was analyzed immunohistochemically in 295 primary epithelial ovarian cancer patients and 67 metastases.A low membranous EMMPRIN expression was detected more often in serous tumors than in other types (p0.0005) and it was associated with tumors of advanced stage (p = 0.012) or with a large primary residual (p = 0.011). A low expression of MMP-2 in cancer cells was associated with a high histologic grade (grade 3) of the tumor (p = 0.005) and endometrioid type of tumors (p0.0005). Stromal MMP-2 expression was significantly associated with strong stromal HA expression (p = 0.002, r = 0.187). In univariate analysis, 10-year disease-related (DRS) and recurrence-free survivals were significantly better when MMP-2 expression in cancer cells was high (p = 0.0057 and p = 0.0467, respectively). DRS was also better when membranous EMMPRIN expression was high (p = 0.013). In multivariate analysis, strong MMP-2 in cancer cells (RR = 1.48, CI = 1.07-2.04, p = 0.017) indicated favorable DRS.Our results show that EMMPRIN and MMP-2 in cancer cells are significant indicators of a favorable prognosis of epithelial ovarian cancer.

In this paper we provide a critical review of research concerned with social/environmental mechanisms that modulate human neuroendocrine function. We survey research in four behavioral systems that have been shaped through evolution: competition, partnering, sex, and pregnancy/parenting. Generally, behavioral neuroendocrine research examines how hormones affect behavior. Instead, we focus on approaches that emphasize the effects of behavioral states on hormones (i.e., the "reverse relationship"), and their functional significance. We focus on androgens and estrogens because of their relevance to sexually selected traits. We conclude that the body of research employing a reversed or bidirectional perspective has an incomplete foundation: participants are mainly heterosexual men, and the functionality of induced shifts in neuroendocrine factors is generally unknown. This area of research is in its infancy, and opportunities abound for developing and testing intriguing research questions.

Women are underrepresented in the professoriate compared to men; this study was designed to examine whether systemic barriers associated with parenting discourage women from pursuing academic careers. Data from 468 female and male graduate students were collected through an online questionnaire. More men than women intend to pursue academic careers. Parenting and mobility issues—but not research or teaching issues—were more negatively associated with entering the professoriate for women than for men. However, women were not more interested in having children than men were. Results support the hypothesis that women self-select away from academia in response to perceived systemic barriers related to parenthood. To ensure quality and equity in academia, universities should enact policy that addresses the realities of childbearing and childrearing women.

Ten polymorphic microsatellite loci were isolated and characterized for the Wood Tiger Moth (Parasemia plantaginis), a nocturnal moth of the Arctiidae family distributed throughout the globe at mid to northerly latitudes. Characterization of 25 P. plantaginis individuals form central Austria showed moderate to high allelic diversity ranging from 2 to 14 alleles per locus. One locus showed significant departures from Hardy-Weinberg equilibrium presumably due to null alleles. No evidence of linkage disequilibrium was found for any locus pair. Polymorphism is also reported in four related Arctiidae species. This set of markers can be useful for the evaluation of genetic composition, conservation, population genetics and might prove useful in other phylogenetically close species of the Arctiidae family.
