Bonk by Mary Roach

Few things are as fundamental to human happiness as sex, and few writers are as entertaining about the subject as Mary Roach. Can a woman think herself to orgasm? Is your penis three inches longer than you think? Why doesn't Viagra help women - or, for that matter, pandas? Does orgasm boost fertility? Or cure hiccups? The study of sexual physiology - what happens, and why, and how to make it happen better - has been taking place behind closed doors for hundreds of years. In this fascinating and funny book, Mary Roach steps inside laboratories, brothels, pig farms, sex-toy R&D labs - even Alfred Kinsey's attic - to tell us everything we wanted to know about sex, and a lot we'd never even thought to ask.

The bestselling author of "Stiff" turns her outrageous curiosity and infectious wit on the most alluring scientific subject of all: sex. In "Bonk," Roach shows how and why sexual arousal and orgasm can be so hard to achieve and what science is doing to make the bedroom a more satisfying place. 16 illustrations.
