Abstract
Recently, mounting anecdotal reports - mostly by heterosexual women on Internet-based dating platforms - have drawn attention to the frequency of men sending unsolicited photos of their own genitals (i.e., "dick pics"). While initial research has documented that the sending of unsolicited nude pictures is fairly common, with generally similar underlying motivations for sending solicited and unsolicited images, understanding recipients' experiences has social-behavioral research, clinical, and potentially legal implications. In a U.S. sample of 2,045 women of all sexual identities and 298 gay/bisexual men, we found that among those who had ever received a "dick pic", nearly all (91%) had also received an unsolicited "dick pic." Women of all sexual identities predominantly experienced negative responses to these unsolicited nude images, with only a minority selecting any positive or neutral/ambivalent reactions. Additionally, women who experienced more unsolicited advances from men in the last year were more likely to select multiple negative reactions, and younger (vs. older) women selected more negative and neutral/ambivalent responses. Conversely, gay and bisexual men responded positively, with few choosing any negative or neutral/ambivalent responses. Findings highlight gendered dynamics of unsolicited sexting and misaligned reactions to male senders, raising questions about sexual harassment in the digital age.

Abstract
Although academic and popular interest in consensual nonmonogamy (CNM) is increasing, little is known about the prevalence of CNM. Using two separate U.S. Census based quota samples of single adults in the United States (Study 1: n = 3,905; Study 2: n = 4,813), the present studies show that more than one in five (21.9% in Study 1; 21.2% in Study 2) participants report engaging in CNM at some point in their lifetime. This proportion remained constant across age, education level, income, religion, region, political affiliation, and race, but varied with gender and sexual orientation. Specifically, men (compared to women) and people who identify as gay, lesbian, or bisexual (compared to those who identify as heterosexual) were more likely to report previous engagement in CNM. These findings suggest that a sizable and diverse proportion of U.S. adults have experienced CNM, highlighting the need to incorporate CNM into theoretical and empirical therapy and family science work.

Abstract
Background: The transmission of sexual images and messages via mobile phone or other electronic media (sexting) has been associated with a variety of mostly negative social and behavioural consequences. Research on sexting has focussed on youth, with limited data across demographics and with little known about the sharing of private sexual images and messages with third parties. Methods: The present study examines sexting attitudes and behaviours, including sending, receiving, and sharing of sexual messages and images, across gender, age, and sexual orientation. A total of 5805 single adults were included in the study (2830 women; 2975 men), ranging in age from 21 to 75+ years. Results: Overall, 21% of participants reported sending and 28% reported receiving sexually explicit text messages; both sending and receiving 'sexts' was most common among younger respondents. Although 73.2% of participants reported discomfort with unauthorised sharing of sexts beyond the intended recipient, of those who had received sext images, 22.9% reported sharing them with others (on average with 3.17 friends). Participants also reported concern about the potential consequences of sexting on their social lives, careers, and psychosocial wellbeing. Conclusion: Views on the impact of sexting on reputation suggest a contemporary struggle to reconcile digital eroticism with real-world consequences. These findings suggest a need for future research into negotiations of sexting motivations, risks, and rewards.

Abstract
Individuals in the early stage of intense romantic love show many symptoms of substance and non-substance or behavioral addictions, including euphoria, craving, tolerance, emotional and physical dependence, withdrawal and relapse. We have proposed that romantic love is a natural (and often positive) addiction that evolved from mammalian antecedents by 4 million years ago as a survival mechanism to encourage hominin pair-bonding and reproduction, seen cross-culturally today in Homo sapiens. Brain scanning studies using functional magnetic resonance imaging support this view: feelings of intense romantic love engage regions of the brain’s “reward system,” specifically dopamine-rich regions, including the ventral tegmental area, also activated during drug and/or behavioral addiction. Thus, because the experience of romantic love shares reward pathways with a range of substance and behavioral addictions, it may influence the drug and/or behavioral addiction response. Indeed, a study of overnight abstinent smokers has shown that feelings of intense romantic love attenuate brain activity associated with cigarette cue-reactivity. Could socially rewarding experiences be therapeutic for drug and/or behavioral addictions? We suggest that “self expanding” experiences like romance and expanding one’s knowledge, experience and self-perception, may also affect drug and/or behavioral addiction behaviors. Further, because feelings of romantic love can progress into feelings of calm attachment, and because attachment engages more plastic forebrain regions, there is a rationale for therapies that may help substance and/or behavioral addiction by promoting activation of these forebrain systems through long-term, calm, positive attachments to others, including group therapies. Addiction is considered a negative (harmful) disorder that appears in a population subset; while romantic love is often a positive (as well as negative) state experienced by almost all humans. Thus, researchers have not categorized romantic love as a chemical or behavioral addiction. But by embracing data on romantic love, it’s classification as an evolved, natural, often positive but also powerfully negative addiction, and its neural similarity to many substance and non-substance addictive states, clinicians may develop more effective therapeutic approaches to alleviate a range of the addictions, including heartbreak–an almost universal human experience that can trigger stalking, clinical depression, suicide, homicide, and other crimes of passion.

Abstract
Mate preference research has focused on traits people desire in partners (i.e., dealmakers) rather than what traits they avoid (i.e., dealbreakers), but mate preferences calibrate to both maximize benefits and minimize costs. Across six studies ( N > 6,500), we identified and examined relationship dealbreakers, and how they function across relationship contexts. Dealbreakers were associated with undesirable personality traits; unhealthy lifestyles in sexual, romantic, and friendship contexts; and divergent mating strategies in sexual and romantic contexts. Dealbreakers were stronger in long-term (vs. short-term) relationship contexts, and stronger in women (vs. men) in short-term contexts. People with higher mate value reported more dealbreakers; people with less-restricted mating strategies reported fewer dealbreakers. Consistent with prospect and error management theories, people weighed dealbreakers more negatively than they weighed dealmakers positively; this effect was stronger for women (vs. men) and people in committed relationships. These findings support adaptive attentional biases in human social cognition.

Abstract
A new temperament construct based on recent brain physiology literature has been investigated using the Fisher Temperament Inventory (FTI). Four collections of behaviors emerged, each associated with a specific neural system: the dopamine, serotonin, testosterone, and estrogen/oxytocin system. These four temperament suites have been designated: (1) Curious/Energetic, (2) Cautious/Social Norm Compliant, (3) Analytical/Tough-minded, and (4) Prosocial/Empathetic temperament dimensions. Two functional magnetic resonance imaging (fMRI) studies have suggested that the FTI can measure the influence of these neural systems. In this paper, to further the behavioral validation and characterization of the four proposed temperament dimensions, we measured correlations with five variables: (1) gender; (2) level of education; (3) religious preference; (4) political orientation; (5) the degree to which an individual regards sex as essential to a successful relationship. Subjects were 39,913 anonymous members of a US Internet dating site and 70,000+ members in six other countries. Correlations with the five variables characterize the FTI and are consistent with mechanisms using the proposed neuromodulators. We also report on an analysis between the FTI and the NEO-Five Factor Inventory, using a college sample (n = 215), which showed convergent validity. The results provide novel correlates not available in other questionnaires: religiosity, political orientation, and attitudes about sex in a relationship. Also, an Eigen analysis replicated the four clusters of co-varying items. The FTI, with its broad systems and non-pathologic factors complements existing personality questionnaires. It provides an index of some brain systems that contribute to temperament, and may be useful in psychotherapy, business, medicine, and the legal community.

Abstract
Despite general perceptions of committed romantic relationships as the most satisfying context with which to engage in sexual activity, acceptance of casual sexual contexts has increased in recent years. Yet little research has examined sexual and emotional satisfaction outside of the committed relationship context. Further, most satisfaction research has focused exclusively on heterosexual samples. The present study aimed to investigate sexual and emotional satisfaction derived from seven sexual relationship contexts and note similarities or differences based on gender and sexual orientation. Data were drawn from an online survey of 6,955 sexually diverse participants. Sexual satisfaction was stronger than emotional satisfaction within casual sex contexts (one night stand, first date, sex with a friend, and hookups) than within more committed contexts (married, living together, committed unmarried relationship). Men found all contexts except for sex in a committed unmarried relationship significantly more sexually and emotionally satisfying than women. Emotional and sexual satisfaction were significantly different across sexual orientation groups in casual sexual relationship contexts but not in more committed relationship contexts. Gay men reported gaining the most sexual and emotional satisfaction out of casual sex contexts, with lesbian women reporting the least out of casual sexual contexts. Overall, this research found that a wide variety of relationship contexts, including casual sexual contexts, can be a source of both sexual and emotional satisfaction.

Abstract
This paper proposes that mammals exhibit three primary emotion categories for mating and reproduction: (1) the sex drive, or lust, characterized by the craving for sexual gratification; (2) attraction, characterized by increased energy and focused attention on one or more potential mates, accompanied in humans by feelings of exhilaration, "intrusive thinking" about a mate, and the craving for emotional union with this mate or potential mate; and (3) attachment, characterized by the maintenance of close social contact in mammals, accompanied in humans by feelings of calm, comfort, and emotional union with a mate. Each emotion category is associated with a discrete constellation of neural correlates, and each evolved to direct a specific aspect of reproduction. The sex drive is associated primarily with the estrogens and androgens; it evolved to motivate individuals to seek sexual union. The attraction system is associated primarily with the catecholamines; it evolved to facilitate mate choice, enabling individuals to focus their mating effort on preferred partners. The attachment system is associated primarily with the peptides, vasopressin, and oxytocin; it evolved to motivate individuals to engage in positive social behaviors and assume species-specific parental duties.During the evolution of the genus Homo, these emotion systems became increasingly independent of one another, a phenomenon that contributes to human mating flexibility and the wide range of contemporary human mating and reproductive strategies.

Abstract
INTRODUCTION Despite recent advances in understanding orgasm variation, little is known about ways in which sexual orientation is associated with men's and women's orgasm occurrence. AIM To assess orgasm occurrence during sexual activity across sexual orientation categories. METHODS Data were collected by Internet questionnaire from 6,151 men and women (ages 21-65+ years) as part of a nationally representative sample of single individuals in the United States. Analyses were restricted to a subsample of 2,850 singles (1,497 men, 1,353 women) who had experienced sexual activity in the past 12 months. MAIN OUTCOME MEASURES Participants reported their sex/gender, self-identified sexual orientation (heterosexual, gay/lesbian, bisexual), and what percentage of the time they experience orgasm when having sex with a familiar partner. RESULTS Mean occurrence rate for experiencing orgasm during sexual activity with a familiar partner was 62.9% among single women and 85.1% among single men, which was significantly different (F1,2848 = 370.6, P < 0.001, η(2) = 0.12). For men, mean occurrence rate of orgasm did not vary by sexual orientation: heterosexual men 85.5%, gay men 84.7%, bisexual men 77.6% (F2,1494 = 2.67, P = 0.07, η(2) = 0.004). For women, however, mean occurrence rate of orgasm varied significantly by sexual orientation: heterosexual women 61.6%, lesbian women 74.7%, bisexual women 58.0% (F2,1350 = 10.95, P < 0.001, η(2) = 0.02). Lesbian women had a significantly higher probability of orgasm than did either heterosexual or bisexual women (P < 0.05). CONCLUSIONS Findings from this large dataset of U.S. singles suggest that women, regardless of sexual orientation, have less predictable, more varied orgasm experiences than do men and that for women, but not men, the likelihood of orgasm varies with sexual orientation. These findings demonstrate the need for further investigations into the comparative sexual experiences and sexual health outcomes of sexual minorities.

Abstract
Theory and research on partnered parents suggests trade-offs between parenting and sexuality, with those trade-offs most pronounced among mothers of young children. However, little research has focused on how a growing demographic of single parents negotiates dating and sexual activity. The current study drew upon a 2012 nationally representative sample of 5,481 single Americans 21 years of age and older, of whom 4.3% were parents of a child age five or younger. Dependent variables were sexual thoughts, frequency of sexual activity, number of sexual partners in the past year, dates during the previous three months, and whether one was actively seeking a relationship partner. Covariates included parental age, sex/gender, sexual orientation, education, and income. Using the entire sample of singles, we found no main effects of number (0, 1, 2+) of children aged five years and younger or number of children aged two years and younger on dating and sexual behavior variables. Next, using analyses restricted to single parents (n = 2,121), we found that single parents with a child aged five years or younger, adjusting for covariates, reported greater frequency of sexual activity and first dates but no differences in other outcomes compared with single parents of older children.

Abstract
Four suites of behavioral traits have been associated with four broad neural systems: the 1) dopamine and related norepinephrine system; 2) serotonin; 3) testosterone; 4) and estrogen and oxytocin system. A 56-item questionnaire, the Fisher Temperament Inventory (FTI), was developed to define four temperament dimensions associated with these behavioral traits and neural systems. The questionnaire has been used to suggest romantic partner compatibility. The dimensions were named: Curious/Energetic; Cautious/Social Norm Compliant; Analytical/Tough-minded; and Prosocial/Empathetic. For the present study, the FTI was administered to participants in two functional magnetic resonance imaging studies that elicited feelings of love and attachment, near-universal human experiences. Scores for the Curious/Energetic dimension co-varied with activation in a region of the substantia nigra, consistent with the prediction that this dimension reflects activity in the dopamine system. Scores for the Cautious/Social Norm Compliant dimension correlated with activation in the ventrolateral prefrontal cortex in regions associated with social norm compliance, a trait linked with the serotonin system. Scores on the Analytical/Tough-minded scale co-varied with activity in regions of the occipital and parietal cortices associated with visual acuity and mathematical thinking, traits linked with testosterone. Also, testosterone contributes to brain architecture in these areas. Scores on the Prosocial/Empathetic scale correlated with activity in regions of the inferior frontal gyrus, anterior insula and fusiform gyrus. These are regions associated with mirror neurons or empathy, a trait linked with the estrogen/oxytocin system, and where estrogen contributes to brain architecture. These findings, replicated across two studies, suggest that the FTI measures influences of four broad neural systems, and that these temperament dimensions and neural systems could constitute foundational mechanisms in personality structure and play a role in romantic partnerships.

Abstract
The present study examined the neural correlates of long-term intense romantic love using functional magnetic resonance imaging (fMRI). Ten women and 7 men married an average of 21.4 years underwent fMRI while viewing facial images of their partner. Control images included a highly familiar acquaintance; a close, long-term friend; and a low-familiar person. Effects specific to the intensely loved, long-term partner were found in: (i) areas of the dopamine-rich reward and basal ganglia system, such as the ventral tegmental area (VTA) and dorsal striatum, consistent with results from early-stage romantic love studies; and (ii) several regions implicated in maternal attachment, such as the globus pallidus (GP), substantia nigra, Raphe nucleus, thalamus, insular cortex, anterior cingulate and posterior cingulate. Correlations of neural activity in regions of interest with widely used questionnaires showed: (i) VTA and caudate responses correlated with romantic love scores and inclusion of other in the self; (ii) GP responses correlated with friendship-based love scores; (iii) hypothalamus and posterior hippocampus responses correlated with sexual frequency; and (iv) caudate, septum/fornix, posterior cingulate and posterior hippocampus responses correlated with obsession. Overall, results suggest that for some individuals the reward-value associated with a long-term partner may be sustained, similar to new love, but also involves brain systems implicated in attachment and pair-bonding.

Abstract
Romantic rejection causes a profound sense of loss and negative affect. It can induce clinical depression and in extreme cases lead to suicide and/or homicide. To begin to identify the neural systems associated with this natural loss state, we used functional magnetic resonance imaging to study 10 women and 5 men who had recently been rejected by a partner but reported they were still intensely "in love." Participants alternately viewed a photograph of their rejecting beloved and a photograph of a familiar, individual, interspersed with a distraction-attention task. Their responses while looking at their rejecter included love, despair, good, and bad memories, and wondering why this happened. Activation specific to the image of the beloved occurred in areas associated with gains and losses, craving and emotion regulation and included the ventral tegmental area (VTA) bilaterally, ventral striatum, medial and lateral orbitofrontal/prefrontal cortex, and cingulate gyrus. Compared with data from happily-in-love individuals, the regional VTA activation suggests that mesolimbic reward/survival systems are involved in romantic passion regardless of whether one is happily or unhappily in love. Forebrain activations associated with motivational relevance, gain/loss, cocaine craving, addiction, and emotion regulation suggest that higher-order systems subject to experience and learning also may mediate the rejection reaction. The results show activation of reward systems, previously identified by monetary stimuli, in a natural, endogenous, negative emotion state. Activation of areas involved in cocaine addiction may help explain the obsessive behaviors associated with rejection in love.

Abstract
Characteristics of bisexually-active men were compared with those of their homosexually-active counterparts in a study of HIV-seropositive men who have sex with men (MSM). Men who had had sex with women in the prior year were younger and more likely to be African American than those reporting sex only with men. They reported higher levels of internalised homophobia and less participation in the gay community. They tended to be recruited through friend referral rather than public sex environments or AIDS service organisations. However, they did not seek sex partners from different venues than other participants. Implications for HIV transmission risk-reduction interventions for this population are discussed.

Abstract
Mammals and birds regularly express mate preferences and make mate choices. Data on mate choice among mammals suggest that this behavioural 'attraction system' is associated with dopaminergic reward pathways in the brain. It has been proposed that intense romantic love, a human cross-cultural universal, is a developed form of this attraction system. To begin to determine the neural mechanisms associated with romantic attraction in humans, we used functional magnetic resonance imaging (fMRI) to study 17 people who were intensely 'in love'. Activation specific to the beloved occurred in the brainstem right ventral tegmental area and right postero-dorsal body of the caudate nucleus. These and other results suggest that dopaminergic reward and motivation pathways contribute to aspects of romantic love. We also used fMRI to study 15 men and women who had just been rejected in love. Preliminary analysis showed activity specific to the beloved in related regions of the reward system associated with monetary gambling for uncertain large gains and losses, and in regions of the lateral orbitofrontal cortex associated with theory of mind, obsessive/compulsive behaviours and controlling anger. These data contribute to our view that romantic love is one of the three primary brain systems that evolved in avian and mammalian species to direct reproduction. The sex drive evolved to motivate individuals to seek a range of mating partners; attraction evolved to motivate individuals to prefer and pursue specific partners; and attachment evolved to motivate individuals to remain together long enough to complete species-specific parenting duties. These three behavioural repertoires appear to be based on brain systems that are largely distinct yet interrelated, and they interact in specific ways to orchestrate reproduction, using both hormones and monoamines. Romantic attraction in humans and its antecedent in other mammalian species play a primary role: this neural mechanism motivates individuals to focus their courtship energy on specific others, thereby conserving valuable time and metabolic energy, and facilitating mate choice.

Abstract
Mammals and birds have evolved three primary, discrete, interrelated emotion-motivation systems in the brain for mating, reproduction, and parenting: lust, attraction, and male-female attachment. Each emotion-motivation system is associated with a specific constellation of neural correlates and a distinct behavioral repertoire. Lust evolved to initiate the mating process with any appropriate partner; attraction evolved to enable individuals to choose among and prefer specific mating partners, thereby conserving their mating time and energy; male-female attachment evolved to enable individuals to cooperate with a reproductive mate until species-specific parental duties have been completed. The evolution of these three emotion-motivation systems contribute to contemporary patterns of marriage, adultery, divorce, remarriage, stalking, homicide and other crimes of passion, and clinical depression due to romantic rejection. This article defines these three emotion-motivation systems. Then it discusses an ongoing project using functional magnetic resonance imaging of the brain to investigate the neural circuits associated with one of these emotion-motivation systems, romantic attraction.

Abstract
Data on divorce taken for all available years between 1947 and 1981 from the Demographic Yearbooks of the United Nations on 58 peoples illustrate that divorce has a consistent pattern. Divorces exhibit a skewed distribution, characterized by the occurrence of the mode early in marriage (with a divorce peak on or around the fourth year) and a gradual, long-tailed decline following this peak. Divorce risk peaks in age category 25-29 for males and age categories 20-24 and 25-29 for females, the height of reproductive and parenting years, and divorce counts peak among couples with two or fewer children. These properties of divorce are unrelated to divorce rate; they occur in societies with both high and low divorce rates. Data on available horticultural and gathering/hunting societies illustrate that divorce also peaks among young couples early in marriage. Remarriage by divorced and widowed individuals of reproductive age is also common cross-culturally. It is proposed that the above four-year modal marriage duration among couples of reproductive age who divorce reflects a hominid reproductive strategy that probably evolved some time after the appearance of Homo in response to increased female "reproductive burden" and functioned to ensure the survival of the hominid infant through weaning. Serial pairbonding during the female's reproductive years had ancestral adaptive advantages, producing the modern cross-cultural pattern of serial pairbonding.
