Recent reviews of the acquired immunodeficiency syndrome in the United States have emphasized a concern regarding the potential spread of human immunodeficiency virus (HIV) infection from current high-risk groups to sexually active heterosexual men and women.1-3 These reviews have also indicated that information about the sexual practices of American men and women, needed for effective epidemic forecasting and the planning of control strategies, is inadequate.
Data regarding selected sexual practices of single men in San Francisco are available from the San Francisco Men's Health Study,4 a prospective study of HIV infection and the acquired immunodeficiency syndrome in a cohort of 1034 single men 25 to 54 years of age obtained by probability sampling from a 6-km-square area of the city.The Table shows the numbers and proportions of male and female sexual partners of homosexual, bisexual, and heterosexual members of the study cohort
