Why is the penis shaped like that?

In this book, Jesse Bering presents over thirty of his essays from Scientific American and Slate, along with two new pieces.

He delves into various aspects of human behavior and evolution, discussing topics such as the adaptive functions of the female orgasm, the neurology of people attracted to animals, and the evolution of human body fluids.

Bering's writing is characterized by his irreverence and humor as he examines a wide range of quirky and fascinating aspects of being human.
