Mothers and fathers of tomorrow's women have little idea what their daughters are up to sexually or how they feel about it. Dr. Terri talks with Peggy Orenstein, author of The New York Times best-selling book "Girls and Sex," about the new sexual landscape girls face, high school through college. Drawing on in-depth interviews with over seventy young women ages 15 - 20 as well as a wide range of experts, Orenstein paints a complex, sometimes disturbing, ultimately hopeful picture of today's young women when it comes to sex.
