The sex lives of unmarried men.

This study of 4,600 unmarried men between the ages of twenty-one and twenty-eight includes data on virginity rates in unmarried men, age of first sex relations, masturbation rates, rates of continued masturbation into adult life, and incidence of homosexuality in this male population. It attempts to correlate these rates with education, economic status, and religious denomination and to estimate the sexual activity of unmarried females. It also reports the markedly different sex mores of the Negro population.
