Since Darwin's day, we've been told that sexual monogamy comes naturally to our species.

But this narrative is collapsing....

The study of sexual physiology has been a paying career or a diverting sideline for scientists as far-ranging as Leonardo da Vinci and James Watson. The research has taken place behind the closed doors of laboratories, brothels, MRI centers, pig farms, sex-toy R&D labs, and Alfred Kinsey's attic.

Mary Roach, "The funniest science writer in the country", devoted the past two years to stepping behind those doors. In Bonk, Roach shows us how and why sexual arousal and orgasm can be so hard to achieve and what science is doing to slowly make the bedroom a more satisfying place.

Why are women more verbal than men? Why do women remember details of fights that men can't remember at all?

In her shocking exposé, You're Teaching My Child What?, Dr. Miriam Grossman rips back the curtain on sex education today, exposing a sordid truth.

This message traumatized many girls - resulting in anxiety, fear, and experiences that mimicked the symptoms of post-traumatic stress disorder - and trapped them in a cycle of shame.
