Cynthia Nixon"Sex and the City" star Cynthia Nixon was in a 15 year relationship with a man before partnering with education activist Christine Marinoni. Said Nixon in 2007: "In terms of sexual orientation I don't really feel I've changed... I'd been with men all my life, and I'd never fallen in love with a woman. But when I did, it didn't seem so strange. I'm just a woman in love with another woman."
