A jaw-dropping re-evaluation of everything we thought we knew about men, women, and sex. Men are biologically programmed to want sex with lots of different women, whereas women are designed to stay true to one person, right?Wrong. In Untrue, New York Times -bestselling author Wednesday Martin reveals that we are just at the beginning of understanding women's sexuality properly. From New York to Namibia to a conference of sex researchers in Montreal, she takes us on a journey to understand women who refuse monogamy, posing questions about why we became sexually exclusive in the first place. Martin attends all-female sex parties where married straight women fulfill their fantasies; considers contemporary societies where women take many lovers; analyses how the invention of the plough suppressed female autonomy; and presents fascinating research about why women stray (their motivations are not so different from men's). Frank and myth busting, Untrue validates the desires of women everywhere, including the 'silent majority' in committed relationships who struggle with staying faithful.
