Sex Sells. Should We Buy? Surprised to find teenagers having sex in a public parking lot in the middle of the afternoon, the author sets out to discover why this bothers him, why we are so controlled by sex and how he can do something about it. The journey starts in a bar in Ireland and takes us on a tour of pop culture, erotic biblical passages, searches for shark teeth, and the most up-to-date scholarship on the sexual behavior of American twenty-somethings. The answers he finds are both profound and practical, and will change more than just our sex lives.
