In this hip, hilarious and truly eye-opening cultural history, menstruation is talked about as never before. Flow spans its fascinating, occasionally wacky and sometimes downright scary story: from mikvahs (ritual cleansing baths) to menopause, hysteria to hysterectomies - not to mention the Pill, cramps, the history of underwear, and the movie about puberty they showed you in 5th grade. Flow answers such questions as: What's the point of getting a period? What did women do before pads and tampons? What about new drugs that promise to end periods - a hot idea or not? Sex during your period: gross or a turn-on? And what's normal, anyway? With color reproductions of (campy) historical ads and early (excruciating) femcare devices, it also provides a fascinating (and mind-boggling) gallery of this complex, personal and uniquely female process.
