Naturally Selective

<P>Researchers of human behaviour have identified an ¿orgasm gap¿: Men usually orgasm during intercourse, whereas women often do not. This book addresses this mystery. The two leading explanations are either that women are ¿psychologically broken¿ - Freud¿s theory ¿ or badly designed ¿ the ¿by-product theory.¿ 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.</P><P>Key Features</P><P>¿                     Synthesizes decades of peer-reviewed sex research in anatomy, biology, physiology and behavior</P><P>¿            &n
