The role of adolescent sexual behavior in educational attainment has been overlooked. Homosexual and heterosexual men were interviewed to test for a correlation between adolescent sexual activeness and educational attainment, as well as any link between childhood masculine sex roles and early sexual activity. Approximately 1,000 volunteers, stratified by age, sex, race, and education to obtain matched samples, answered questions about their education, frequency of adolescent heterosexual and homosexual experience, high school academic performance, adolescent sociability, parents' education, relative attachment to parents, and present sexual orientation. Results indicated that while early sexual activity did not affect performance in high school, it did affect attitudes toward further education after leaving high school. This suggests that attitudes developed through adolescent sexual involvement become operative after graduation when individuals are faced with a choice between marriage and further education. Findings also supported a positive correlation between childhood masculine interests and early sexual intercourse. (LP)
