men who have sex with men

Men who engage in such sexual activity but do not necessarily self-identify as homosexual or bisexual. Often abbreviated as "MSM." In the medical community, use of the term "men who have sex with men" has been seen as a way to more accurately ascertain disease rates, by focusing on one's actual sexual activity, rather than their sexual identity.
