If a charity can be simultaneously sexy and socially aware — like Al Gore in a corset — these girls can pull it off. The Aqua Foundation for Women raises money for breast cancer and promotes equality for lesbian, bisexual, and transgender ladies. But don't get them wrong: These chicks know how to throw a bash. Take, for example, a certain sex-crazed, booze-soaked annual lesbian pool party. Volunteer at their annual weeklong event, Aqua Girl, and count on making friends. You'll help with comedy shows, live music, and a jazz brunch, to name just a few events, with smart and witty gals. You'll talk about culture, global affairs, sex, more sex, politics, and — naturally — women. They'll make you want to do some good, damn it.
