Over the course of five years, Freitas—no longer a full-time professor—has lectured extensively and expanded her research. The result is The End of Sex: How Hookup Culture Is Leaving a Generation Unhappy, Sexually Unfulfilled, and Confused About Intimacy. Aimed more at popular audiences, this book leaves aside the soul and focuses on the sex. Specifically, it examines the hookup culture at secular and Catholic universities, the roles that culture trains men and women to play, and how students can opt out of hooking up.
