Women's sexuality: behaviors, responses, and individual differences.

Classic and contemporary approaches to the assessment of female sexuality are discussed. General approaches, assessment strategies, and models of female sexuality are organized within the conceptual domains of sexual behaviors, sexual responses (desire, excitement, orgasm, and resolution), and individual differences, including general and sex-specific personality models. Where applicable, important trends and relationships are highlighted in the literature with both existing reports and previously unpublished data. The present conceptual overview highlights areas in sexual assessment and model building that are in need of further research and theoretical clarification.

Effects of antisense to the (alpha)2A-adrenoceptors administered into the region of the locus ceruleus on behaviors in plus-maze and sexual behavior tests in sham-operated and castrated male rats.

Clinical and experimental findings have implicated brain alpha2-adrenoceptors in the regulation of many physiological functions, including sexual activity and stress-related behavior. However, which subtypes of the three alpha2-adrenoceptors that have now been cloned (alpha2A, alpha2B, and alpha2C) are involved in these controls have yet to be established. Here, we investigated the contribution of alpha2A-adrenoceptors of the locus ceruleus, the principal source of brain noradrenaline, to exploratory and sexual behaviors. Using administration of antisense oligodeoxynucleotide to inhibit the receptor expression, we found that reductions in brainstem alpha2A-adrenoceptor mRNA levels and alpha2-adrenoceptor densities induced by antisense treatment were not accompanied by any changes in the major characteristics of male sexual activity, such as mount latencies and numbers of mounts. However, in sexual behavior tests, antisense-treated male rats had decreased numbers of rearings and thus have higher percentages of behaviors positively correlated with sexual activity. Besides, antisense-treated animals had decreased anxiety in plus-maze tests. The data demonstrate that inhibition of alpha2A-adrenoceptor expression in the region of the locus ceruleus has an anxiolytic-like effect and facilitates male's attention to female in sexual behavior test.

Sexual behavior in adults with autism.

A survey of the sexual behavior of 89 adults with autism living in group homes in North Carolina found that the majority of individuals were engaging in some form of sexual behavior. Masturbation was the most common sexual behavior. However, person-oriented sexual behaviors with obvious signs of arousal were also present in one third of the sample. The relationship between sexual behavior and demographic variables and other types of behaviors is explored. Information regarding group home sexuality policies and procedures are described.

Is there a reliable and valid self-report measure of sexual behavior?

A psychometric analysis of the Sexual Experience Scale (SES) from the Derogatis Sexual Functioning Inventory was conducted. This sexual behavior measure was administered on four occasions to a large sample of normal, heterosexual, sexually active women and a comparable sample which underwent gynecologic treatment that resulted in a predictable and clinical level of sexual dysfunction. In terms of reliability, internal consistency estimates for the SES were in the .85 to .90 range, but the stability of the SES was lower and ranged from .55 to .85. An evaluation of the validity revealed both strengths and limitations of the SES. The content analysis reveals that a wider range of sexual behaviors is sampled by the SES than comparable measures. To examine construct validity, a factor analysis provided a five-factor solution which would account for 82% of the variance, but the solution was not stable across groups or time and the factors were not sensitive to detecting important behavior changes. As many other psychological measures, the SES was poor in predicting a criterion (i.e., the occurrence of sexual dysfunction) concurrently or at the time of follow-up. The outcome of this analysis is discussed in the context of selecting reliable and valid self-report measures of sexual behavior.

Dopamine and serotonin: influences on male sexual behavior.

Steroid hormones regulate sexual behavior primarily by slow, genomically mediated effects. These effects are realized, in part, by enhancing the processing of relevant sensory stimuli, altering the synthesis, release, and/or receptors for neurotransmitters in integrative areas, and increasing the responsiveness of appropriate motor outputs. Dopamine has facilitative effects on sexual motivation, copulatory proficiency, and genital reflexes. Dopamine in the nigrostriatal tract influences motor activity; in the mesolimbic tract it activates numerous motivated behaviors, including copulation; in the medial preoptic area (MPOA) it controls genital reflexes, copulatory patterns, and specifically sexual motivation. Testosterone increases nitric oxide synthase in the MPOA; nitric oxide increases basal and female-stimulated dopamine release, which in turn facilitates copulation and genital reflexes. Serotonin (5-HT) is primarily inhibitory, although stimulation of 5-HT(2C) receptors increases erections and inhibits ejaculation, whereas stimulation of 5-HT(1A) receptors has the opposite effects: facilitation of ejaculation and, in some circumstances, inhibition of erection. 5-HT is released in the anterior lateral hypothalamus at the time of ejaculation. Microinjections of selective serotonin reuptake inhibitors there delay the onset of copulation and delay ejaculation after copulation begins. One means for this inhibition is a decrease in dopamine release in the mesolimbic tract.

Comparison of sexual behaviors between male homosexuals and male heterosexuals in Taiwan.

BACKGROUND: Homosexuality and sexual behavior have attracted great attention in the acquired immunodeficiency syndrome (AIDS) epidemic. This study primarily explores the risky behaviors and patterns of sexual behavior of male homosexuals in Taiwan. METHODS: Comparison study methodology was adopted. Ninety-two male homosexuals, as the study group, were recruited from gay bars and gay organizations, and 91 male heterosexuals, with similar ages and educational levels, were recruited as a control group for comparison. Semi-structured interviews were carried out and anonymous questionnaires were self-administered. RESULTS: (1) The mean age at the time of first sexual intercourse of the study group was younger than that of the control group. (2) The rate of having two or more sexual partners in the study group was significantly higher. (3) However, the rate of condom use during recent intercourse was higher in the control group than in the study group. (4) Sexual knowledge and attitudes toward sexuality in the study group were more open, but their sexual desires, as rated by the questionnaire, were more suppressed than those of the control group. (5) In terms of courtship, the study group was less constrained by the social values of marriage and tended to separate sex from love. CONCLUSION: Similar to western studies, our study found that the study group in Taiwan adopted more risky sexual behaviors. Each group had its particular sexual behavioral pattern and subculture of sexuality. However, a longitudinal follow-up study with ethnographic perspective is necessary for a more sophisticated understanding of the trends and changes of sexual behavior in homosexuals.

Sexual possibility situations and sexual behaviors among young adolescents: the moderating role of protective factors.

PURPOSE: To examine sexual possibility situations (SPS) and protective practices associated with involvement in intimate sexual behaviors and the initiation of sexual intercourse among young adolescents and to determine if protective factors moderate the relationship between SPS and sexual behaviors. METHODS: Data for these analyses were obtained from the baseline assessment for adolescents conducted as part of an HIV prevention study called "Keepin' it R.E.A.L.!" The study was conducted with a community-based organization (CBO) in an urban area serving a predominantly African-American population. In addition to items assessing SPS, intimate sexual behaviors, and initiation of sexual intercourse, adolescents provided information on the following protective factors: educational goals, self-concept, future time perspective, orientation to health, self-efficacy, outcome expectations, parenting, communication, values, and prosocial activities. Background personal information, including age and gender, was also collected. The analyses were conducted on data from 491 predominantly African-American adolescents, 61% of whom were boys. Variables were combined to form SPS and protective indices that were used in the first set of regression analyses. In a second set of analyses, the indices were unbundled and individual variables were entered into regression analyses. RESULTS: Both SPS and protective indices explained significant portions of variance in intimate sexual behaviors, and the SPS index explained a significant portion of variance in the initiation of sexual intercourse. The regression analysis using the unbundled SPS and protective factors revealed the following statistically significant predictors for intimate sexual behaviors: age, gender, time alone with groups of peers, time alone with a member of the opposite sex, behavior self-concept, popularity self-concept, self-efficacy for abstinence, outcome expectations for abstinence, parental control, personal values, and parental values. A similar regression analysis revealed that age, time alone with a member of the opposite sex, and personal values were significant predictors of initiation of sexual intercourse. CONCLUSIONS: These results provide evidence for the important role of protective factors in explaining early involvement in sexual behaviors and show that protective factors extend beyond personal characteristics to include both familial and peer factors.

Effects of female odors on the sexual behavior of male hamsters.

A series of experiments was undertaken to investigate the effects of removal of several scent glands and scent-producing organs of female hamsters on the copulatory performance of male hamsters. In the first experiment it was shown that males engage in less copulatory activity toward females lacking vaginal secretions than toward females with these odors. Eliminating visual cues by observing pairs under infrared illumination did not change the performance of males toward these two kinds of females. The results of Experiment 2 indicated the importance of flank, ear, and Harderian glands as well as vaginal secretions--males showed the highest levels of copulatory behavior toward females with a full complement of odors and the lowest levels toward those lacking three of four sources of scent. Similar results were obtained in the third experiment in which anesthetized females were used as stimulus animals to increase the importance of chemical cues and to reduce variability due to the behavior of females. The sexual behavior of males was greatest toward females with all sources of scent present, lower toward those lacking vaginal secretions, and still lower toward those lacking vaginal secretions and other sources of odors. In the fourth experiment we asked whether any one of the nonvaginal scent glands was particularly important in stimulating male sexual behavior, but we found no differences in male performance toward females that lacked vaginal secretions or that in addition lacked one of the other scent glands. In the fifth experiment males displayed higher levels of sexual behavior toward vaginectomized females than toward vaginectomized females that had been deodorized by a cleaning procedure, again indicating the importance of nonvaginal odors in stimulating copulatory performance. Thus these experiments demonstrate the importance of vaginal secretions in the sexual arousal of male hamsters, a role for nonvaginal odors in sexual arousal of males, and the lack of necessity of these odors for male copulatory behavior. These results have implications for theories of olfactory communication in mammals and for interpretations of experiments in which lesions of the olfactory system lead to deficits in male copulatory performance.

Naltrexone suppresses abnormal sexual behavior in Tourette's syndrome.

Abnormal sexual behavior occurs in 30-40% of patients with Tourette's syndrome (TS). Two patients with TS who exhibited distressing abnormal sexual behavior experienced amelioration of symptoms with administration of the oral opiate receptor antagonist naltrexone (TrexanR). Conventional anti-TS drugs including haloperidol and clonidine were ineffective. Abnormal sexual behavior may be another feature of the disease responding to opiate blockers.

Sexual behavior of infertile couples.

The role of sexual dysfunction was evaluated among 98 couples during infertility examination. The wife and the husband were interviewed separately and together. Sixty-six women were willing to report daily their sexual behavior in association with recording basal body temperature. Male sexual dysfunction was the primary cause of infertility in five couples (5%). Three pregnancies resulted after examination and simultaneous supportive discussion. Following a simple diary on sexual behavior, 19 of 66 women conceived (29%). Fourteen of these 19 women reported orgasm within two days preceding elevated basal body temperature. Open discussion about sex was possibly therapeutic. Infertility examinations should include an evaluation of the sexual behavior of couples, with special reference to frequency and timing of coitus.

Vomeronasal organ: critical role in mediating sexual behavior of the male hamster.

Sexual behavior in male hamsters is totally abolished by bilateral removal of the olfactory bulbs. This operation eliminates sensory input from both the olfactory and the vomeronasal systems. We previously demonstrated that peripheral destruction of the olfactory receptors caused anosmia but did not impair male hamster mating behavior. Here we demonstrate that peripheral deafferentation of the vomeronasal system produces severe sexual behavior deficits in approximately one-third of the treated animals. Combined deafferentation of both the vomeronasal and the olfactory systems eliminates copulation in 100 percent of the animals. This is the first experimental demonstration of a functional role for the vomeronasal organ in a mammalian species.

Child sexual behavior inventory: A Dutch-speaking normative sample.

OBJECTIVES: To describe normative sexual behavior in Dutch-speaking children; to assess the frequencies of different types of sexual behaviors reported in children by their parents; to analyze the relation of these sexual behaviors to demographic, personal, familial, and general behavioral variables; and to compare the Dutch-speaking sample with American samples. METHOD: Nine hundred seventeen children (2-12 years of age), screened to exclude sexual abuse, were rated by their caregiver via parent report consisting of the translated Dutch version of the Child Sexual Behavior Inventory, the Child Behavior Checklist, a life event checklist, and a questionnaire assessing family nudity and parental attitudes regarding sexuality. RESULTS: Frequencies of a wide variety of sexual behaviors for 2- to 5-, 6- to 9-, and 10- to 12-year-old children are presented. Sexual behavior was found to be related to the child's age, maternal education, family nudity, and parental attitudes toward sexuality. The positive relation to general behavioral problems was confirmed. Findings were primarily similar to previously published American studies. CONCLUSION: Our study confirms that sexual behavior in children is varied and related to developmental, personal, and familial factors. The relative frequency of the wide variety of sexual behaviors in a Dutch-speaking normative sample is comparable to American samples.

Sexual revictimization: the role of sexual self-esteem and dysfunctional sexual behaviors.

Disproportionately high rates of sexual revictimization have been noted among former victims of child sexual abuse (CSA), yet researchers have yet to determine the source of this apparent vulnerability to reexperience sexual violence. This study explores this issue by examining sexual self-esteem, sexual concerns, and sexual behaviors among 402 university women. Compared to women without a history of CSA (n = 348), women with a history of CSA (n = 54) had lower sexual self-esteem, poorer sexual adjustment, and were 2 times more likely to have experienced sexual assault since the age of 14 years. Structural equation modeling indicated that the relationship between child abuse (i.e., CSA and child psychological maltreatment) and sexual revictimization was partially mediated by sexual self-esteem, sexual concerns, and high-risk sexual behaviors. This study emphasizes the need for further research on child maltreatment, revictimization, and women's sexual adjustment.

A review of sexual behavior in the United States.

OBJECTIVE: Knowledge of sexual behavior in the United States is necessary for 1) directing risk-reduction interventions aimed at preventing transmission of human immunodeficiency virus (HIV) and other sexually transmitted pathogens and 2) appreciating the current normative patterns of sexual behavior. METHODS: The authors reviewed American surveys that included measures of sexual behavior and analyzed the 1988-1990 General Social Surveys. RESULTS: Most American males have intercourse by 16-17 years of age, and females do so by 17-18 years of age. The majority of young adults aged 18-24 have multiple, serial sex partners. Among adults 25-59 years old, relative monogamy appears to be the norm: 80% of heterosexually active men and 90% of heterosexually active women in this age group report having had only one sex partner in the preceding year. The average frequency of intercourse among such monogamous individuals is one to three times per week. Approximately 25% of adults have had heterosexual anal intercourse. Up to 20% of adult men report that they have had a homosexual experience; 1%-6% report such an experience during the preceding year. CONCLUSIONS: Through accumulated studies, data are now available on normative sexual behavior across the life cycle. Such data should assist in psychiatric diagnosis and in the development of treatment goals that rely on assumptions regarding normative behavior. A large proportion of young heterosexual persons are at considerable risk for sexually transmitted disease. Sexual history taking and risk-reduction counseling should be integral components of psychiatric care.

A prospective study of intraindividual and peer influences on adolescents' heterosexual romantic and sexual behavior.

Theories and empirical studies of adolescent sexual behavior have identified the contributions of personal attributes and social experiences; however, it is rare that models have clarified developmental pathways to adolescent sexual behavior that include (1) factors assessed prior to and early in adolescence and (2) dyadic experiences in adolescence that provide the opportunity for sexual behavior (i.e., dating). Using data from a prospective study, structural equation modeling was used to test a model predicting adolescent sexual behavior at age 19, denoted by the number of lifetime sexual partners. Predictors examined were sociability and impulsivity assessed at 30 months of age, physical characteristics and experiences with peers measured at age 12-13, the age of first romantic relationship, and frequency of alcohol use at age 16. The pathway to greater sexual involvement was marked by some desired personal attributes (e.g., sociability) and peer experiences (e.g., higher quality friendships). These associations were mediated, however, by earlier initiation of romantic relationships and more frequent use of alcohol in middle adolescence. Earlier initiation of romantic relationships and more frequent alcohol use were predicted by greater sociability and less impulsivity in childhood, higher quality friendships and greater peer acceptance in early adolescence, and a more mature appearance and physical attractiveness (among females) at age 13. The findings imply a complex pathway that leads to a greater accumulation of sexual partners by age 19. This pathway begins in childhood and includes individual qualities, peer acceptance, romantic relationships, and alcohol use.

A comparison of sexual behavior and self-esteem in young adult females with positive and negative tests for sexually transmitted diseases.

Contracting sexually transmitted diseases is a serious health problem faced by young women, in part, because they may routinely engage in risky sexual behaviors. This study describes the sexual behaviors of eighty-one young adult females who had positive and negative tests for STDs. The STD-negative group consisted of forty-nine African American females and the STD-positive group was thirty African American and two Caucasian females. The women completed the Safe Sex Behavior Questionnaire and the Rosenberg Self Esteem Scale. Demographic factors were also examined. The findings revealed that STD-negative females had higher self esteem and practiced safe sex more frequently. Also, women with higher education and incomes above $10,000 a year, plus a higher self-esteem level scored higher on the SSBQ, indicating the practice of safer sex. Age was not related to self esteem or the practice of safe sexual behavior. Implications for nurse practitioner practice are discussed.

Exposure to degrading versus nondegrading music lyrics and sexual behavior among youth.

BACKGROUND: Early sexual activity is a significant problem in the United States. A recent survey suggested that most sexually experienced teens wish they had waited longer to have intercourse; other data indicate that unplanned pregnancy and sexually transmitted diseases are more common among those who begin sexual activity earlier. Popular music may contribute to early sex. Music is an integral part of teens' lives. The average youth listens to music 1.5 to 2.5 hours per day. Sexual themes are common in much of this music and range from romantic and playful to degrading and hostile. Although a previous longitudinal study has linked music video consumption and sexual risk behavior, no previous study has tested longitudinal associations between the content of music lyrics and subsequent changes in sexual experience, such as intercourse initiation, nor has any study explored whether exposure to different kinds of portrayals of sex has different effects. DESIGN AND PARTICIPANTS: We conducted a national longitudinal telephone survey of 1461 adolescents. Participants were interviewed at baseline (T1), when they were 12 to 17 years old, and again 1 and 3 years later (T2 and T3). At all of the interviews, participants reported their sexual experience and responded to measures of more than a dozen factors known to be associated with adolescent sexual initiation. A total of 1242 participants reported on their sexual behavior at all 3 time points; a subsample of 938 were identified as virgins before music exposure for certain analyses. Participants also indicated how frequently they listened to each of more than a dozen musical artists representing a variety of musical genres. Data on listening habits were combined with results of an analysis of the sexual content of each artist's songs to create measures of exposure to 2 kinds of sexual content: degrading and nondegrading. OUTCOME MEASURES: We measured initiation of intercourse and advancement in noncoital sexual activity level over a 2-year period. RESULTS: Multivariate regression analyses indicated that youth who listened to more degrading sexual content at T2 were more likely to subsequently initiate intercourse and to progress to more advanced levels of noncoital sexual activity, even after controlling for 18 respondent characteristics that might otherwise explain these relationships. In contrast, exposure to nondegrading sexual content was unrelated to changes in participants' sexual behavior. CONCLUSION: Listening to music with degrading sexual lyrics is related to advances in a range of sexual activities among adolescents, whereas this does not seem to be true of other sexual lyrics. This result is consistent with sexual-script theory and suggests that cultural messages about expected sexual behavior among males and females may underlie the effect. Reducing the amount of degrading sexual content in popular music or reducing young people's exposure to music with this type of content could help delay the onset of sexual behavior.

Modern day influences on sexual behavior.

To better understand temporal trends in sexual behavior and their determinants, it is important to look at the demographic and technologic context in which we live; both affect sexual behaviors. Mental disorders and CSA emerge as important correlates of high-risk sexual behaviors. The changing role and expectations of women-the result of major economic and social transformation-transform society further through changes to family and community structures. These changes occur alongside increasing inequality and upheavals in the world, all of which are more visible through increased mobility and communication in the "global village." Changes in sexual norms, relationships, abuse, and mental health are better understood in the context of this broad political background.
