In the introductory essays by Sharon Link, Francis Duffy, and Carolyn Sprague, readers receive a broad overview of contemporary conceptions of sexuality and sexual behavior. Sprague analyzes the ever-changing social and cultural norms of sex by detailing the “sexual revolution” of the 1960s and the resultant liberalization of sexuality. The shift in societal perspectives and the newfound tolerance of sexual practices, as she explains, “have exacted a cost on society and contributed to the spread of STDs and AIDS.” A contributing factor of the newfound sexual freedom of the age is the pervasive use of contraception, specifically “the Pill.” Geraldine Wagner highlights how “modern contraception has caused a social revolution in the history of humankind.” One of the greatest changes in sexual activity, according to Sprague, is the increase in teenage intercourse and sexual practices, which results in a host of problems and challenges, chief among them teen pregnancy and sexually transmitted diseases. In a transitional essay, Maureen McMahon reflects on the subject of media and sexuality by examining how popular culture and social networking sites have an effect on mainstream attitudes shared by teenagers and young adults.
