Important Purpose

The effectiveness of sex to make children is remarkably low and totally random: there is no doubt that as soon as possible other methods to achieve it will be preferred. Yet humans have an enormous amount of sexual relations, devote a great deal of their resources to it, and most of the time seek to ensure that they are not fertile. Why? The usual explanations are insufficient to explain these behaviors. This article proposes that the most important purpose of sexual intercourse is to transmit not our genes but the genes of our microbiome, that is of other species’ genes. This hypothesis explains not only the frequency of sexual intercourse but also the frequency of non-fertilizing and risky sexual behaviors.

Sex in one of its many forms is an almost universal human experience. Given its ubiquity and its potential for widespread health impacts, understanding the determinants of sexual behaviors has become a topic of considerable scientific investigation. Sex is often a highly emotionally charged experience, so it is perhaps unsurprising that certain affective states have been shown to be closely tied to particular sexual behaviors. This chapter begins by briefly describing the evidence for why sex should be considered an important health behavior, including the health benefits associated with certain sexual behaviors and risks associated with others, and then outlines the research on some of the affective determinants of sexual behaviors. Specific topics include how emotional states predict sexual intercourse frequency and sexual arousal, the interplay of mood and sex in the context of romantic relationships, and affective determinants of risky sexual behaviors.

The objective is to present risky sexual behaviors that can lead to contracting sexually transmitted infections (STIs). In San Luis Potosí, Mexico, a universe of 77 men with active sexual life was studied; a self-administered questionnaire with four sections was applied: initiation of sexual intercourse, sexually transmitted diseases, preventive actions and number of sexual partners. To measure sexual behavior, two scales were designed, an ordinal one to observe different levels, a nominal one for the presence or absence of risky sexual behaviors. Some results obtained show that 87.1% had their first sexual intercourse at age 18 or earlier, 53.2% always used condoms, 93.5% had their first sexual intercourse with women and 6.5% with men, and 63.7% engaged in risky sexual behavior. One of the conclusions is that the majority of males in this study engaged in one or more risky sexual behaviors that can lead to contracting HPV and other sexually transmitted diseases

Abstracts Background Sexual risk behaviors are defined as sexual activities that may make an individual liable to the risk of sexually transmitted infections including Human Immunodeficiency virus (HIV) and unplanned pregnancies. Adolescents are at high risk of developing sexual risk behavior. The rate of risky sexual behaviors and the spread of STIs continue to be increase among the adolescent population. Therefore this study aimed to assess Metu secondary and preparatory school adolescent knowledge, attitude, and practice of risky sexual behaviors. Methods Institution based descriptive cross sectional study was conducted among Metu secondary and preparatory school students from 04 Feb 2019–07 June 2019. The study participants were selected through systematic random sampling techniques and the data was collected through self-administered questionnaires. A Total of 361 study subjects were included in the study. Data was entered in EpiData and analyzed by using SPSS version 21. Results Three hundred sixty one respondents participated in this study. Of those, 75.9% of them have awareness about risky sexual behaviors and about 76.5. % of them has awareness on consequences of unsafe sex. Among the total study participants, about 22.7% of them had previously practiced in sexual activity; of these 61.7% of respondents had more than one sexual partner. From the respondents who had practiced sex, 19.8% of them had always used condom during their sexual intercourse with their partners, while 58% of them never used condom during sexual intercourse. Conclusions Even though the majority of the students have an awareness regarding sexual risk behaviors, a considerable number of students have practiced risky sexual behaviors that might predispose them for different sexual and reproductive health problems and peer pressure was revealed as a major factor that influences the respondents towards their first sexual intercourse. Peers have greater influence on the positive and negative behavior of their friends. Therefore the school should emphasize on promoting peer educators and peer discussion to protect adolescents and youth from risky sexual behaviors.

Sex With Men

Studies investigating the association between early sexual debut and human immunodeficiency virus (HIV) infection have mainly focused on Africans or females but rarely on men who have sex with men (MSM) in China. This study, therefore, mainly aimed at exploring the association between early sexual debut and HIV infection among MSM in Shenzhen, China. A total of 533 MSM were enrolled in this study using a convenience sampling method. Information about sociodemographic characteristics and risky sexual behaviors was collected. It was found that the prevalence of HIV infection was 24.2% among this study population and 66.4% of the MSM reported having had vaginal sexual intercourse with females. The mean ages at first vaginal sexual intercourse, first anal sexual intercourse, and first sexual intercourse were 21.38, 22.43, and 19.87 years, respectively. Multivariable logistic regression analyses showed that the MSM who experienced early anal sexual debut were more likely to be infected with HIV than those who did not. The results indicate that HIV infection is quite prevalent among MSM in Shenzhen. Early and efficient intervention strategies should be taken, and the MSM experiencing early anal sexual debut should be given special attention.

Early Sexual Intercourse

Purpose: The purpose of this study was to investigate sexting practice among students and identify the risky sexual behaviors associated with sexting among students in Machakos University, Machakos County, Kenya. Methodology: The study adopted a descriptive cross-sectional study design. The target sample was 347 students aged 18-24 years in Machakos university. Convenience sampling was used for quantitative data and purposive sampling for qualitative data as well as the study area. Interviewer-administered questionnaires were utilized and in-depth interview used for the qualitative data collection. The IBM SPSS version 26.0 was used for data analysis. Thematic analysis was used to analyze the qualitative data and triangulated with quantitative findings. Results was presented in tables, graphs and pie charts. Chi square test was done to identify variables associated with sexting and odds ratio to measure the association between sexting and risky sexual behavior. Findings: Sexting (sending of sexually suggestive image/photo) was found to be prevalent among the student at 57% and 48% being two-way sexters. Male respondents engaged more into sexting as compared to female respondents at 67%and 33% respectively.23.0% sexted to keep or get a boy/girlfriend and 14% due to pleasure from their peers. Gender, Age, Level of study and relationship status were all significantly associated with sexting (P=0.000, P=0.027, P=0.002 and P=0.022 respectively). Risky sexual behaviors among students included early sexual intercourse 74%, but 54% had not used protection. Sexting and risky sexual behavior were found to be associated because most of the respondents who engaged in sexting were eight times more like to engage in early sexual intercourse, and the perception of sexters was that if one was sexting they were six times likely to have sex with the person they sexted, and so the null hypothesis that there is no relationship between sexting and risky sexual behavior was rejected and the alternative hypothesis adopted. Unique contribution to theory, practice and policy: Adoption of Multi sectoral to develop policies, and design youth programs with a wide range of issues relating to sex and sexuality and how to safely navigate the internet and form healthy relationships both on and offline, which include issues such as sexting with young people from a young age.

First Sexual Intercourse

Abstract Studies show that the age of first sexual intercourse is directly correlated with risky sexual behavior among civilian populations. However, few studies have looked at the age of first intercourse and its consequence among soldiers. A study was conducted to examine the age of first sexual experience and sexual practices among soldiers surveyed at a large military post. The survey consisted of 31 fixed-choice items that focused on the soldiers’ sexual knowledge, beliefs and behaviors. A total of 450 soldiers were included in the sample. Respondents were divided into three main categories by age groupings of first sexual experience as follows: under 14 years of age, between the ages of 14 to 17 years, and over 18 years. All values were analyzed using frequency distributions with calculations of means, standard deviations, and range. Results showed that soldiers who had their first sexual experience under the age of 14 were more likely to participate in risky sexual behaviors than those whose first sexual experience occurred when soldiers were over the age of 18.

Abstract Background North Carolina bears a high burden of HIV and was ranked number 8 for the number of new infections in 2015. In 2014, the Centers for Disease Control and Prevention (CDC) published updated practice guidelines recommending the use of pre-exposure prophylaxis (PrEP) with daily oral dosing of tenofovir/emtricitabine to help prevent HIV infection in high-risk individuals. However, the use of PrEP in the primary care setting remains low and 1 in three primary care physicians is not aware of PrEP. The objective of our study was to evaluate PrEP knowledge among primary care resident physicians. Methods 149 resident physicians were surveyed at East Carolina University from the following specialties; Internal Medicine, Medicine-Pediatrics, Obstetrics Gynecology and Family Medicine. We collected participants’ age, biological sex, current residency program, and current year within the residency program. Results Sixty out 149 residents completed the online survey. 20% of residents had never heard of PrEP. 17% of residents did not feel comfortable discussing sexual preferences with their patients. 15% of residents thought prescribing would increase risky sexual behaviors and 12% would not prescribe PrEP to patients with multiple sexual partners. Only 3% of residents identified potential side effects of PrEP (e.g., an increase in creatinine levels or decrease in mineral bone density) as a reason to not prescribe PrEP. One resident had ever prescribed PrEP. 83% of residents wanted more information on PrEP and 95% of residents would be willing to prescribe PrEP if educational workshops were offered. Conclusion PrEP is an underutilized tool among resident physicians in Eastern, NC. We identified lack of knowledge of PrEP and concern for increased risky sexual behaviors as barriers to prescribing. Resident physicians require more education on PrEP in order to prescribe it to their patients. Disclosures All authors: No reported disclosures.
