The Social Organization of Sexuality, a report on the nation's most comprehensive representative survey of sexual behavior in the general population to date, finally offers that basic information. Conducted by a research team centered at the University of Chicago, the National Health and Social Life Survey (NHSLS) was designed to determine the incidence and prevalence of sexual practices and to place them in their social contexts. Based on personal interviews with a probability sample of 3,432 American women and men between the ages of 18 and 59, undertaken by the National Opinion Research Center, this study explores the extent to which sexual conduct and general attitudes toward sexuality are influenced by gender, age, marital status, and other demographic characteristics. The results of this survey both allow us to better understand how sexual behavior is organized in American society, and offer significant implications for policymakers struggling with many of the nation's crucial health problems. In exploring the rate of new partner formation, for example, the researchers discovered that about 80% of American adults had only one or no sexual partner in the past year. By concentrating AIDS awareness information on the 20% of the population that had two or more partners. AIDS strategists would be better able to target and persuade this segment of the population to modify their sexual behavior. Other topics covered by the survey include early sexual experiences, masturbation, contraception and fertility, abortion, sexual abuse, coercion, sexual health, satisfaction, and sexual dysfunction. A wide variety of sexual practices and preferences are also explored in the questionnaire, including specific questions on homosexual desire, identity, and behavior, the appeal of various sexual practices, and their frequency and incorporation into sexual lives.
