Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus , or anus and rectum , for sexual pleasure. While anal sex is commonly associated with male homosexuality , research shows that not all gay males engage in anal sex and that it is not uncommon in heterosexual relationships. As with most forms of sexual activity, anal sex participants risk contracting sexually transmitted infections STIs. Anal sex is considered a high-risk sexual practice because of the vulnerability of the anus and rectum. The anal and rectal tissues are delicate and do not provide lubrication like the vagina does , so they can easily tear and permit disease transmission, especially if a personal lubricant is not used. Strong views are often expressed about anal sex.
Condomless Anal Intercourse Among Males and Females at High Risk for Heterosexual HIV Infection.
Anal sex - Wikipedia
Anal intercourse poses a greater risk for HIV transmission than vaginal intercourse, and in recent years there has been a growing understanding that heterosexual anal intercourse HAI is not uncommon. However, the majority of the anal intercourse literature has focused on men who have sex with men. The little research on HAI has mostly looked at women, with limited work among men. Almost half of the sample was non-Hispanic Black. Men who reported HAI were more likely to be Hispanic, homeless, had a male partner, engaged in sex exchange, and used cocaine or amphetamines during sex.

Relationship status is an important factor associated with condomless anal intercourse CAI amongst men who have sex with men MSM. Our results speak to the need to consider segmented and tailored public health and health promotion initiatives for MSM with differing CAI behaviours and relationship profiles. In order to develop and implement community-level risk-reduction initiatives targeting MSM, it is necessary to examine not only key sexual behaviours amongst different MSM sub populations, but to also understand and consider the context in which they occur; relationships are one such context. Nevertheless, examining explanatory factors related to differences in CAI between MSM in steady and casual relationships can be important in order to interrogate segmented public health and health promotion initiatives for MSM with differing sexual behaviour and relationship profiles.
Metrics details. Our study aims to find whether MSM who were recruited online had a higher prevalence of self-reported unprotected anal intercourse UAI than those who were recruited offline. A meta-analysis was conducted from the results of published studies.
