Men who have sex with men MSM , also known as males who have sex with males , are male persons who engage in sexual activity with members of the same sex, regardless of how they identify themselves. The term MSM was created in the s by epidemiologists to study the spread of disease among men who have sex with men, regardless of identity. It does not describe any specific sexual activity, and which activities are covered by the term depends on context. First, it was pursued by epidemiologists seeking behavioral categories that would offer better analytical concepts for the study of disease-risk than identity-based categories such as "gay", " bisexual ", or "straight" , because a man who self-identifies as gay or bisexual is not necessarily sexually active with men, and someone who identifies as straight might be sexually active with men. Second, its usage is tied to criticism of sexual identity terms prevalent in social construction literature which typically rejected the use of identity-based concepts across cultural and historical contexts.

And although not everyone agrees that a male orgasm without ejaculation is a "true" orgasm, techniques for achieving multiple non-ejaculatory orgasms abound, for example in tantric sex practices. I guess "enough" is as good as a feast. Guys fake orgasms too — they just do it less often than women. A study of male and female college students showed that of students who had had vaginal intercourse, 28 percent of the men and 67 percent of the women had faked it before.

The sexual behaviors of bisexually active men, defined as men having sex with a man and a woman in previous 6 months, were compared with men who had sex with men only. Differential sexual practices associated with HIV risk between the two groups of men, as well as in the bisexual men with their male and female partners, were evaluated. Cross-sectional analyses were performed on baseline data from a prospective cohort of young gay men recruited from bars, college campuses, and a health center in Boston from to The two groups had similar levels of unprotected anal intercourse

There are many stereotypes that portray men as sex-obsessed machines. Books, television shows, and movies often feature characters and plot points that assume men are crazy about sex and women are only concerned with romance. So what stereotypes about the male sex drive are true?
