Girls Gone Wild. “Cardio Striptease.” Tank tops for preteens declaring them “juicy.” Ariel Levy looks at the ways porn has gyrated itself into the mainstream with her new book, Female Chauvinist Pigs: Women and the Rise of Raunch Culture. Today’s young women might giggle as they take it all off in the name of sexual freedom, but to Levy, the joke is still on them. “We have to ask ourselves why we are so focused on silent girly-girls in G-strings faking lust. This is not a sign of progress, it’s a testament to what’s still missing from our understanding of human sexuality with all of its complexity and power.” Is the dark side of commodified “girl power” finally revealing itself? Levy speaks at 1 p.m. at Politics and Prose, 5015 Connecticut Ave. NW. Free. (202) 364-1919. (Rachel Beckman)
