It has launched both purity balls and porn franchises, defines a young woman's morality-but has no medical definition. Enter the magical world of virginity, where a white wedding dress can restore a woman's innocence and replacement hymens can be purchased online. Filmmaker Therese Shechter uses her own path out of virginity to explore why our sex-crazed society cherishes this so-called precious gift. Along the way, we meet sex educators, virginity auctioneers, abstinence advocates, and young men and women who bare their tales of doing it-or not doing it. "How To Lose Your Virginity" uncovers the myths and misogyny surrounding a rite of passage that many obsesses about but few truly understand.
