Why Is Sex Fun?

The Evolution of Human Sexuality

Physiologist Jared Diamond explores how human sexual practices evolved into unique biological traits compared to those of other mammalian species. The book examines the evolutionary reasons behind concealed ovulation, recreational copulation outside fertile windows, menopause, and pair bonding. Drawing upon evolutionary biology and anthropology, Diamond illuminates why these unusual behavioral patterns helped modern humans successfully reproduce and raise offspring.
