Changes in American sexual behavior brought about by the sexual revolution have been linked to the breakdown of the family and other social ills. Because sex has profound consequences for self, others, and society, sex education is an important part of character education. Sexual abstinence before marriage is associated with better physical and psychological health among adolescents and adults, fosters stable marriages, and ensures that childbearing takes place within marriage. Because abstinence education encourages students to avoid all risk taking and make sexual choices that are objectively in their best interest and the best interest of society, it is the approach most aligned with the goals of character education. Recent reviews of research have identified abstinence education programs that have been effective in reducing teen sexual activity. Consideration is given to how to provide continued support for sexual restraint during the college years.
