This article examines adolescent understanding of the social context of sex
ual behavior. Using grounded theory to interpret interviews with 39 African
American male and female adolescents, the article builds a model of sex-re
lated behavior as a set of interrelated games. A courtship game involves co
mmunication of sexual or romantic interest and, over time, formation of a r
omantic relationship. A duplicity game draws on conventions of a courtship
game to trick a partner into having sex. A disclosure game spreads stories
about one's own and others' sex-related activities to peers in a gossip net
work. Finally, a prestige game builds social reputation in the eyes of peer
s, typically based on gender-specific standards. The article concludes by e
xamining the meanings that sex-related behavior may have for adolescents an
d the potential use of social knowledge for facilitating adolescent health.
