In The Age of Sex, Decker demonstrates how maturation became defined as the hypothetical moment when a girl becomes a woman capable of engaging in heterosexual activity and a boy becomes a man imbued with the right and responsibility to have heterosexual intercourse. Colonial ethnographic studies reduced complex precolonial rites of passage to “puberty rites” fixated on these sexual transformations. The resulting stereotypes influenced, in turn, how colonial and postcolonial court officials decided age-of-consent and other sex crime cases. Court rituals thus legally transformed girls into women by ruling on their sexual maturity and boys into men by sentencing them to corporal punishment, marking their acceptance of heterosexual responsibilities.
