For over a decade, battles have raged between conservative Abstinence Only Until Marriage (AOUM) sexuality education advocates and liberal Comprehensive Sexuality Education (CSE) advocates. While these battles have focused on the inclusion of health information about contraception and whether or not a curriculum must advocate abstinence as the best and only method to avoid pregnancy and sexually transmitted diseases, these debates have often ignored other important values about sex. In this article, Sharon Lamb reviews the recent history of these sexuality education battles, criticizes both AOUM and CSE curricula, and discusses how, in CSE's accommodation to AOUM objections, ethical dimensions of sex education may have been neglected in favor of evidence-based practice. She then suggests ways in which the current curricula could teach ethical reasoning and make sex education a form of citizenship education, focusing on justice, equity, and caring for the other person as well as the self.
