Frequency Of Sexual Behaviors Research Articles

Male Hatano low-avoidance rats show more active sexual behavior with lower plasma testosterone than high-avoidance rats.

Two inbred strains of Sprague-Dawley rats, known as the Hatano high- and low-avoidance animals (HAA and LAA respectively), have been selectively bred for high versus low rates of avoidance responses in a shuttle-box avoidance task. To investigate differences in the sexual behavior of Hatano rats, male HAA, LAA and SD rats were tested from 12 to 15 weeks of age. LAA rats exhibited more rapid and frequent sexual behavior than HAA or SD rats, and such differences increased with repeated sexual experience. Plasma testosterone levels tended to be lower in LAA rats than in HAA or SD rats, suggesting that active sexual behavior in LAA rats is not related to these levels. Strain differences in mating behavior between HAA and LAA rats may be caused by emotional responses to novelty.

A Framework for Categorizing Chronically Problematic Sexual Behavior

ABSTRACTThis article introduces a framework for categorizing chronically problematic sexual behavior. It identifies patterns of commitment violations, values conflicts, diminished self-control, negative consequences, and lack of sexual responsibility as independent categories of chronically problematic sexual behavior. It recognizes that many forms of problematic sexual behavior can be reduced or eliminated by changing either sexual or nonsexual components of a person's life. This framework does not use the type or frequency of sexual behavior as an assessment variable. It neither postulates causes of problematic sexual behavior nor offers techniques for its reduction or elimination. This framework does not replace any existing theories or assistance models. Since it is capable of supporting theories representing many different perspectives, it expands the potential for interdisciplinary collaboration to widen the range of options available to more people who want to reduce or eliminate chronically problematic aspects of their sexual behavior.

Symbolic meanings of sex in relationships: Developing the Meanings of Sexual Behavior Inventory.

Consistent with symbolic interactionism and motivation research, the study explored the meanings of sexual behavior in romantic relationships in a sample of 3,003 online respondents. Starting with a pool of 104 respondent-generated items, Exploratory and Confirmatory Factor analyses in separate sample halves revealed a stable set of 9 dimensions within that item pool that formed 2 higher-order factors representing positive (to share pleasure, to bond, to de-stress, to energize the relationship, to learn more about each other) and negative (to manage conflict, as an incentive, to express anger, and to control partner) meanings of sexual behavior within relationships. Item Response Theory analyses helped select the 4-5 most effective items of each dimension for inclusion in the Meanings of Sexual Behavior Inventory (MoSBI). Generalizability analyses suggested that the MoSBI subscale scores continued to show high levels of internal consistency across a broad range of demographic subgroups (e.g., racial/ethnic groups, gay and lesbian respondents, and various levels of education). The MoSBI subscales demonstrated moderate and distinct patterns of association with a range of conceptual boundary scales (e.g., relationship and sexual satisfaction, emotional support, negative conflict behavior, and frequency of sexual behavior) suggesting that these scales represent novel relationship processes. Consistent with this, analyses in the 862 respondents completing a 2-month follow-up assessment suggested that the meanings of sexual behavior predicted residual change in relationship satisfaction, even after controlling for frequency of sexual behavior within the relationships. Implications are discussed. (PsycINFO Database Record

Sexual well-being of sexual minority women in dating relationships who have experienced childhood sexual abuse and/or adolescent and adult sexual victimization

Few studies have examined the sexual sequelae of child sexual abuse (CSA) for sexual minority women (SMW), particularly SMW in dating relationships. We examined the impact of CSA on several aspects of sexual well-being. Participants were 299 SMW in a non-cohabiting dating relationship who completed an online survey that assessed CSA, adolescent and adult sexual victimization (AASV) and their behavioural, motivational, and cognitive-affective sexual responses. Four groups were formed based on sexual abuse experiences before the age of 14: No lifetime sexual abuse (NSA Group); AASV only (AASV Group); CSA limited to fondling (CSAfon Group); and, CSA involving attempted/completed vaginal, oral and/or anal penetration (CSApen Group). Women in the CSAfon and CSApen groups were significantly more likely to report having experienced AASV (77% and 56%, respectively) than were women in the AASV and NSA groups (32%). Women in the CSApen Group reported significantly lower sexual desire and sexual satisfaction, and more frequent negative automatic sexual thoughts than women in the other groups but no differences in their frequency of sexual behaviours, sexual duration, sexual esteem, or sexual anxiety. The AASV Group did not differ from the NSA Group on any of the sexual well-being variables. Overall, women in all four groups generally reported positive sexual well-being. These results suggest CSA involving attempted/completed penetration with or without subsequent AASV negatively affects only some aspects of SMW's sexual well-being. They also suggest SMW who have experienced sexual abuse can and do enjoy healthy sexual well-being within the context of a dating relationship.

Child Sexual Behaviors in School Context: Age and Gender Differences

ABSTRACTThe main purpose of the study was to explore the child sexual behaviors that Italian teachers have observed in the school context. A representative sample of 227 children, from 5 to 10 years old, was rated by their teachers through the Child Sexual Behavior Inventory. Frequencies of sexual behaviors among children aged 5 to 6, 7 to 8, and 9 to 10 are presented. Younger children showed a broader range of sexual behaviors that decrease with the growing age, such as males in comparison to females. Moreover, findings showed that child sexual behavior is not only related to age and gender but also to family characteristics. These results suggested that child sexual behaviors reported by teachers through the Child Sexual Behavior Inventory may provide useful information about the development of children’s sexuality. The knowledge of age appropriate sexual behaviors can help teachers discern normal sexual behaviors from problematic sexual behaviors.

What's In an Identity Label? Correlates of Sociodemographics, Psychosocial Characteristics, and Sexual Behavior Among African American Men Who Have Sex With Men.

African American men who have sex with men (AAMSM) are vastly overrepresented among people with HIV/AIDS. Using data from 595 AAMSM in Philadelphia, we explored differences in sociodemographics, psychosocial characteristics related to beliefs about ethnicity, sexuality and masculinity, and sexual behavior with men and women by self-reported sexual identity (gay, bisexual, down low, straight). Roughly equivalent numbers identified as gay (40.6%) and bisexual (41.3%), while fewer identified as straight (7.6%) or down low (10.5%), with significant differences in age, income, history of incarceration, HIV status, alcohol and drug problems, childhood sexual abuse, and connection to the gay community evident among these groups. Analysis of psychosocial characteristics theorized to be related to identity and sexual behavior indicated significant differences in masculinity, homophobia, and outness as MSM. Gay and straight men appeared to be poles on a continuum of frequency of sexual behavior, with bisexual and down low men being sometimes more similar to gay men and sometimes more similar to straight men. The percentage of men having total intercourse of any kind was highest among down low and lowest among gay men. Gay men had less intercourse with women, but more receptive anal intercourse with men than the other identities. There were no significant differences by identity in frequency of condomless insertive anal intercourse with men, but gay men had significantly more condomless receptive anal intercourse. There were significant differences by identity for condomless vaginal and anal intercourse with women. This study demonstrates the importance of exploring differences in types of sex behavior for AAMSM by considering sexual identity.

Characteristics of HIV's sexual behavior and their effect on the secondary transmission rate

To analyze the sexual behavior characteristics of the sexually transmitted HIV-positive people and to estimate the secondary transmission rate. Field investigation and literature review were conducted among sexually transmitted HIV-positive people to collect general information during the last 6 months before notification of HIV infection. A mathematical model was used to estimate the secondary transmission rate. A total of 769 HIV-positive people were recruited for the study, 186 of them were women, 286 were men who have sex with women (MSW), 242 were men who have sex with men (MSM) and 55 were men who have sex with men and women (MSMW). During 6 months, the average sex partner among these 4 groups were 2.29, 1.61, 3.32 and 4.10, respectively; the sexual behavior frequency were 26.03, 20.97, 14.77 and 25.51, respectively; the rates of non-use of condom were 74.14%, 73.53%, 59.60% and 72.06%, respectively; the secondary transmission rate were 0.0095, 0.0151, 0.1759 and 0.1985, respectively. Under constant conditions of other factors, the secondary transmission rates decreased by 30.13%-82.00%, 23.00%-49.51%, and 16.10%-19.09%, respectively, if there was a reduction in 1 sex partner, 1 time/month for the sexual frequency and 20% of rate for non-use of condom. The HIV secondary transmission from MSMW HIV-positive people to general population was the highest. Change in sexual behavior of the HIV-positive people can decrease the HIV secondary transmission rate significantly.

Effect of Photoperiod Extension on the Testicular Sonographic Appearance and Sexual Behavior of Captive Yangtze Finless porpoise (Neophocaena asiaeorientalis asiaeorientalis).

Xueying Yu, Yujiang Hao, Brian CW Kot, and Ding Wang (2016) Photoperiod plays an important role in the seasonal regulation of reproduction in mammals. In the present study, we examined the effect of an extended photoperiod (light/dark: 14 h/10 h) during the usual sexually inactive phase (Jan-Mar) on testicular sonographic appearance and sexual behaviors of two captive Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis, YFP). During the extended photoperiod treatment, the parenchyma pixel intensity, cross- sectional area of testicular sonographic images, as well as the frequency of sexual behaviors of the two male porpoises increased significantly compared to the control treatment. Parenchyma pixel intensity, the cross- sectional area of testicular sonographic images and the frequency of sexual behaviors of the two captive males all increased in response to extended photoperiod. These results may suggest that photoperiod is a potent factor regulating the reproductive seasonality in YFPs.

The Framing of Frequent Sexual Behavior and/or Pornography Viewing as Addiction: Some Concerns for Social Work

SummaryThe application of an addiction framework to frequent sexual behavior and/or pornography viewing has increased significantly in recent years, particularly across North America. Herein, I refer to a multidisciplinary literature to explore critically whether or not application of an addiction framework is warranted.FindingsThe sex/pornography addiction model can be criticized based on the lack of quality scientific evidence to support it, sociocultural biases in interpreting sexual behavior, and assumptions involving diagnostic criteria.ApplicationsWhile social workers should strive to help clients who desire to resolve various personal issues involving sexuality, workers should keep in mind that human sexuality is diverse and avoid using the addiction label.

Sexual Activity After 60: A Systematic Review of Associated Factors

Sexuality and the desire for affection and intimacy are important human features across the lifespan. To evaluate and synthesize the existing literature on factors associated with continued sexual activity in adults at least 60 years of age. Three databases were used to select articles, 57 of which met the selection criteria. Methodologic quality was assessed and data were extracted from these studies by two independent reviewers according to standards proposed by the Cochrane Collaboration. Studies were evaluated for quality, included sexual activities, and identified associated factors. Sexual activity was positively associated with past frequency of sexual behavior and partner's interest in sexual activity. Decreased sexual activity (and/or cessation) was associated with the presence of erectile dysfunction and partner's illness. Noteworthy were significant inconsistencies of findings across studies and contrasting findings of generally assumed factors associated with sexual activity in later years (eg, physical and mental health). However, increasing methodologic quality was observed in studies that were more recent. Probable reasons for disparate findings are discussed and recommendations for methodologic improvements are outlined, focusing on population diversity, construct definitions, measurement, and sampling techniques. The literature on sexual activity in older adults is vastly heterogeneous with methodologic caveats and inconsistent results evidenced across studies. Vigilant attention to methodology is essential because sexual activity in later life is multidetermined with amplified individual variability in older vs younger cohorts.

In this study, we aimed to evaluate the effect of UU hydrolysate powder on sexual activity in vivo. METHODS A total of 50 Sprague-Dawley male rats were divided into five groups. Dried U. unicinctus hydrolysate power was administered to low dose group (LD group, 20mg/kg), intermediate dose group (ID group, 100mg/kg), and high dose group (HD group, 500mg/kg) per oral for 12 weeks. Sexual behavior with estrous ovariectomized female rats was evaluated two times at 8 and 12 weeks from the initiation of treatment. Single dose of tadalafil (0.4mg/kg) were administered to positive control group (PC group) before 24 hours from each experimentations, and negative control group (NC group) were not treated with any medication. At the end of the second experiment, blood sample was obtained to evaluate level of testosterone. RESULTS Frequency of sexual behavior (mount and ejaculation) was significantly increased in LD, ID, and HD groups compared to that in group NC, and comparable to that in group PC (Figure 1, 2). Almost latency time of sexual behavior also was shortened in rats treated with U. unicinctus. A Kruskal-Wallis test indicated that there were not significant differences in level of serum testosterone across groups. CONCLUSIONS This result suggests that Urechis unicinctus is effective to enhance sexual function in male rats. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e1190 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Sung Hyun Paick More articles by this author Woo Suk Choi More articles by this author Dong Yeub Ham More articles by this author Hyoung Keun Park More articles by this author Hyeong Gon Kim More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...

Preliminary Findings On Behavioral Patterns Of The Barking Deer, Muntiacusmuntjak (Zimmermann 1780) In Captivity At Dhaka Zoo In Bangladesh

This research was conducted to document behavioral patterns of the barking deer, Muntiacus muntjak (Zimmermann 1780) in captivity. All-occurrence and ad libitum sampling methods were used opportunistically to observe 15 barking deer at Dhaka Zoo in Bangladesh from April to November, 2011.A total of 54 behavioral patterns of the barking deer was recorded and described under 13 major heads. Of which, 41 behavioral patterns were similar for males and females and 13 were sex different. The highest observation was recorded for self-directed behaviors (21.55%) followed by consuming behaviors (20.84%), investigative behaviors (17.65%), scent markings and depositions (14.53%), relaxed states (13.98%), agonistic interactions (2.63%), foraging behaviors (2.31%), sexual behaviors (1.83%), submissive behaviors (1.66%), elimination (1.25%), movements (1.23%), vocalization (0.3%) and affinitive interactions (0.23%). The behavioral patterns were almost similar for male and female with several patterns showing variations. Females consumed food and took rest more frequently than males, who spent more time in foraging and movement. Males also showed higher frequency of sexual behaviors and less submissive behaviors. Environmental sniffing (n=792) was the most frequently encountered behavior and preaching (n=l) was the least. The present findings reveal that majority of the behaviors resemble that of other cervids, but nibbling and barking are unique to this species.

Phenotypic characteristics and sexual behavior of <i>Sennar</i> Jacks (<i> Equus asinus</i>)

This study was carried out with an objective of evaluating the breeding soundness and sexual behavior of Sennar jackasses. The physical characteristics such as the body weight, height at wither, body condition, and age of the jacks was measured and recorded. The characteristics of sexual behavior as determined by score of the sex derive, and the time taken for erection, first mount and intromission were assessed in the presence of estrous Jennies and recorded before semen collection. The body weight of the jacks range between119 and 380 kg, with mean body condition score of 7 for the breeding and 4.8 for the working jacks. The mean (±SE) of height at wither, the chest girth and the head-tail length were118±5.54 cm, 124.4±2.2 cm, 150.3±1.0 cm, respectively. The frequency of mounting without erection and with erection, time to full erection, time to ejaculation and number of ejaculatorythrust were in the order of 4.62±1.93 and 1.9±0.88, 13.45±7.02 minutes, 23.03±7.78 minutes, 4.21±0.61, respectively. Libido score was mostly (89.5%) strong during the 160 collections. The longest time to ejaculation was 58 minutes. The most frequent sexual behavior was sniffing of the vulva, flehmen, and mounting with or without erection. Flehmen responses and mounts without erection greatly varied among the jacks.The most notable difference from Abyssinian donkeys was the libido, which was relatively stronger in Sennar donkeys. However, they usually took longer time for ejaculation, which is also a common behavior among donkeys as compared to stallions. This study confirms that body characteristics of Sennar donkeys with respect to size are better than other donkey types, and semen collection and AI are feasible procedures for breed improvement in Sennar donkeys.

7α-Hydroxypregnenolone regulates diurnal changes in sexual behavior of male quail

In the Japanese quail, 7α-hydroxypregnenolone, a previously undescribed avian neurosteroid, is actively produced in the brain. 7α-Hydroxypregnenolone acts as a novel neuronal activator to stimulate locomotor activity of quail. Therefore, in this study, we determined whether 7α-hydroxypregnenolone changes the expression of sexual behavior in Japanese quail. We first measured diurnal changes in sexual behavior of male quail exposed to a long-day photoperiod. We found that sexual behavior of male quail was high in the morning when endogenous 7α-hydroxypregnenolone level is high. Subsequently, we centrally administered 7α-hydroxypregnenolone in the evening when endogenous 7α-hydroxypregnenolone level is low. In the 30min after intracerebroventricular (ICV) injection, 7α-hydroxypregnenolone dose dependently increased the frequency of sexual behavior of male quail. However, 7β-hydroxypregnenolone, a stereoisomer of 7α-hydroxypregnenolone, did not effect on the frequency of sexual behavior of male quail. In addition, to confirm the action of 7α-hydroxypregnenolone on sexual behavior, male birds received an ICV injection of ketoconazole, an inhibitor of cytochrome P450s, and behavioral experiments were performed in the morning. Ketoconazole significantly decreased the frequency of sexual behavior of male quail, whereas administration of 7α-hydroxypregnenolone to ketoconazole-treated males increased the frequency of their sexual behavior. These results indicate that 7α-hydroxypregnenolone regulates diurnal changes in sexual behavior of male quail.

Examining associations between sexual behaviours and quality of life in older adults.

while sexual behaviours are potentially important for quality of life in older adults, they are under-researched. The current study examined associations between frequency and importance of sexual behaviours and quality of life in older adults. one hundred and thirty-three participants (mean 74 years, SD = 7.1) provided information about the frequency with which they participated in six sexual behaviours and the perceived importance of these: touching/holding hands, embracing/hugging, kissing, mutual stroking, masturbating and intercourse. Participants also completed the WHO Quality of Life scale, providing an overall quality of life score, in addition to the domains of physical health, psychological health, social relationships and environment. Participants provided information on their marital status, living arrangements and self-reported health. both the frequency and importance of sexual behaviours were moderately positively correlated with quality of life (r = 0.52 and 0.47, respectively, both P < 0.001). In separate regression analyses, the frequency of sexual behaviours was a significant predictor of quality of life in the social relationships domain (β = 0.225, P < 0.05), and the importance of sexual behaviours was associated with the psychological domain (β = 0.151, P < 0.05), independent of the presence of a spouse/partner and self-reported health. with ageing trends, a broader understanding of the factors that influence quality of life in older adults is increasingly important. The current findings suggest that aspects of sexual behaviour and quality of life were positively associated. Researchers are encouraged to consider aspects of sex and sexuality when exploring determinants of well-being in later life.

Sexual self-schema and depressive symptoms after prostate cancer

The years following prostate cancer treatment are characterized by changes in sexual functioning and risk for depressive symptoms. Sexual self-schema (SSS) is a cognitive generalization about sexual aspects of the self that are associated with sexual behavior, affect, and the processing of sexually relevant information. This study tested if men's SSS moderates the impact of sexual morbidity on depressive symptoms. Men (N = 66) treated for localized prostate cancer in the preceding 2 years were assessed at T1 and 4 months later (T2). Questionnaires included the Center for Epidemiologic Studies Depression Scale, Sexual Self-schema Scale for Men, Sexual Experience Scale, and Expanded Prostate Cancer Index Composite. Regressions controlled for age, sexual activity, and T1 depressive symptoms revealed no significant effect of SSS on depressive symptoms; however, better sexual functioning was related to fewer depressive symptoms (B = -0.25, p < 0.05). Results showed significant interactions between SSS and sexual outcomes. Among men with high SSS, poor sexual functioning was associated with increased depressive symptoms; loss of sexual function was particularly distressing. There was no significant effect of sexual functioning. Among men with high SSS, there was an inverse relationship between sexual engagement and depressive symptoms. Among men with lower SSS, greater frequency of sexual behavior was associated with increased depressive symptoms. SSS may be an important individual difference in determining the impact of sexual morbidity on psychological adjustment. Men high on SSS are more vulnerable to psychological consequences of lower sexual functioning and less engagement in sexual activities.

Hypersexual disorder in general practice.

Hypersexual disorder is also termed compulsive sexual disorder, sexual addiction and non-paraphilic sexual disorder, reflecting different approaches to conceptualising its aetiology. Increased frequency of sexual behaviour alone does not indicate pathology. Research suggests that within the population with markedly increased frequency of sexual behaviour, there is a group in whom such behaviour leads to distress and impairment. Patients who experience increased frequency and intensity of sexual behaviour, with accompanying distress and impaired life functioning, may seek medical treatment.

Sex on the beach: the influence of social norms and trip companion on spring break sexual behavior.

Spring Break trips are associated with heavy drinking and with risky sexual behavior (e.g., unprotected sex, multiple partners, unwanted sexual contact), especially for those students who go on trips with friends. The present study adds to this growing event-specific risk literature by examining Spring Break-specific normative perceptions of sexual risk behavior and the role that these perceptions and taking a trip with a friend or with a romantic partner have on Spring Break sexual behavior. College students (N = 1,540; 53.9% female) were asked to report descriptive normative perceptions of sex with casual partners, drinking prior to sex, number of drinks prior to sex, and condom use as well as their own Spring Break drinking and sexual behaviors. Students perceived the typical same-sex student to have engaged in more frequent sexual behavior for all outcomes than students' own self-reported sexual behavior. Furthermore, results revealed that these perceptions were positively associated with behavior. The choice of travel companion (friend(s) versus romantic partner) also differentially predicted sexual behaviors. Results suggested that intervention efforts aimed at reducing risks for Spring Break trip-takers may be strongest when they incorporate corrective normative information and target those traveling with friends.
