The parts of your body that you're supposed to pretend don't exist. You can have a lot of fun with them, assuming you're not Catholic.

Roberta Gregory's raucous girl comic book. Features her signature characters, Bitchy Bitch and Bitchy Butch and touches on many topics from a woman's POV, including: sex, work, men, lesbianism, etc... Quite a good read, for those who are not easily offended.
