Why Is Sex Fun?: The Evolution of Human Sexuality

Excerpt

The subject of sex preoccupies us. It's the source of our most intense pleasures. Often it's also the cause of misery, much of which arises from built-in conflicts between the evolved roles of women and men.

This book is a speculative account of how human sexuality came to be the way it now is. Most of us don't realize how unusual human sexual practices are, compared to those of all other living animals. Scientists infer that the sex life of even our recent apelike ancestors was very different from ours today. Some distinctive evolutionary forces must have operated on our ancestors to make us different. What were those forces, and what really is so bizarre about us?

Understanding how our sexuality evolved is fascinating not only in its own right but also in order to understand our other distinctively human features. Those features include our culture, speech, parent-child relations, and mastery of complex tools. While paleontologists usually attribute the evolution of these features to our attainment of large brains and upright posture, I argue that our bizarre sexuality was equally essential for their evolution.

Among the unusual aspects of human sexuality that I discuss are female menopause, the role of men in human societies, having sex in private, often having sex for fun . . .
