Happy birthday to Maggie Gyllenhaal, one of our favorite actresses, supporters of Planned Parenthood, and outspoken feminists. Jake's older sister, who turns 35 today, is one of the most sex-positive celebrities out there. Last year she hosted a show on Discovery all about the female orgasm, and she followed that up by starring in this year's Hysteria, a film about the invention of the vibrator. And don't forget her role in 2002's Secretary, a film about S&M that happened to have its own Mr. Grey character, à la 50 Shades. Thanks in part to these roles, Maggie has shared some wise words on a range of sexually charged topics. Read on for our favorite quotes from birthday girl Maggie Gyllenhaal!
