Everything you ever wanted to know about sex but were afraid to ask. Literally.

Why do testicles hang the way they do? Is there an adaptive function to the female orgasm? What does it feel like to want to kill yourself? Does 'free will' really exist? And why is the penis shaped like that anyway?

Research psychologist and award-winning columnist Jesse Bering takes readers on a bold and captivating journey through some of the most taboo issues related to evolution and human behaviour. Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality and serious questions about life and death, Bering boldly goes where no science writer has gone before.

With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you're interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current phallic physique, Why Is The Penis Shaped Like That? is bound to create lively discussion and debate for years to come.
