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. It is controversial in various cultures, especially with regard to religious prohibitions.

Participants reported many high-risk sexual and substance use behaviors. Thirteen percent used methamphetamine in the past year. Methamphetamine use was more common among human immunodeficiency virus—infected participants odds ratio, 2. Methamphetamine use is a public health problem with significant implications for the health and well-being of YMSM. Methamphetamine use was associated with human immunodeficiency virus—related risk, and patterns of use were predicted by demographic data, sexualized social contexts, and psychological variables. Crystal methamphetamine is an addictive stimulant with use nationwide that has become a troubling epidemic. The substance has emerged as a significant risk factor for the acquisition of HIV and other sexually transmitted infections. For example, it has been reported that MSM may use methamphetamine as a means of escaping underlying psychological distress such as low self-esteem, loneliness, grief, or depression, each a factor with potential to exacerbate HIV risk in this vulnerable population. In response to growing concerns about methamphetamine use and sexual risk for HIV infection among MSM, in January , the Centers for Disease Control and Prevention sponsored a consultative meeting to identify directions for much-needed methamphetamine-specific research and clinical practice.
