Naturally Selective

Researchers of human behaviour have identified an "e;orgasm gap"e;: Men usually orgasm during intercourse, whereas women often do not. This book addresses this mystery. The two leading explanations are either that women are "e;psychologically broken"e; - Freud's theory - or badly designed - the "e;by-product theory."e; However, there is a much more compelling third explanation. Evolutionary biology, anatomy, physiology, and direct sex research suggest women have evolved under their own selection pressures and orgasm is a fitness-increasing consequence of such selective factors. This is revealed in their patterns of orgasmic response, which are neither random nor inexplicable.Key Features Synthesizes decades of peer-reviewed sex research in anatomy, biology, physiology, and behavior Engagingly written based on feedback from students, peers, and interested lay persons Makes sense of the "e;orgasm gap"e; between men and women Provides a wider context of human sexual dimorphism and mutual sexual selection Balances sex research and real-world research and practical applications.
