In this article, we examine sociodemographic and health correlates of sexual health among HIV-infected men.  Our data came from a prospective cohort study of HIV-infected men (N = 226) in North-Central Florida.  We measured sexual health using self-reports of sexual activity, erectile function, sex drive, and sex life satisfaction.  Better sexual health was present among men who were younger, non-White, cohabiting, and infected through homosexual sex.  In addition, men with fewer comorbid conditions, better self-reported health, and less depression had better sexual health.  Sexual health was stable for the majority of participants; yet, when change occurred, it was typically for the worse.  Decreased sexual health was associated with being older, not cohabiting, lower socioeconomic status, becoming HIV-infected through homosexual sex, ill physical health, and depression.  Our paper demonstrates the benefits of longitudinal analyses for understanding sociodemographic and health variation in sexual activity, erectile function, sex drive, and sex life satisfaction.
