A New York Times Bestseller

"Rich in dexterous innuendo, laugh-out-loud humor and illuminating fact. It's compulsively readable." —Los Angeles Times Book Review

In Bonk, the best-selling author of Stiff turns her outrageous curiosity and insight on the most alluring scientific subject of all: sex. Can a person think herself to orgasm? Why doesn't Viagra help women—or, for that matter, pandas? Can a dead man get an erection? Is vaginal orgasm a myth? Mary Roach shows us how and why sexual arousal and orgasm—two of the most complex, delightful, and amazing scientific phenomena on earth—can be so hard to achieve and what science is doing to make the bedroom a more satisfying place.
