Drug-using men who have sex with men: Sexual behaviours and sexual identities

Men who have sex with men (MSM) and use drugs are at high risk for HIV. This study assessed drug and sex-related risk behaviours and sexual identities for MSM drug injectors and crack smokers. One hundred and forty four MSM drug injectors and crack smokers from ®ve USA cities were interviewed. One-third of the men were current injectors, twice as many reported lifetime injection. Most (56%) reported sex with women in the prior year; sex trading was reported by 32 % with males and 53 % with females. There were signi®cant differ-ences between private and public sexual identities. For example, while 31 % reported being behaviourally bisexual, only 17 % identi®ed themselves to others as bisexual. Drug using MSM are clearly a heterogenous group and prevention messages addressing this diversity are needed
