2. It's Okay to Expose All to Your Girlfriends
Women talked about sex with their friends long before SATC. But the show gave us permission on a large scale to get graphic and detailed in cathartic and hilarious ways. It was like a six-season long Consciousness Raising group with better outfits.
This seems especially true when it comes to discussing self-pleasuring; it's now much more socially acceptable for women to admit they do it ("I'm getting carpal tunnel syndrome"), and even talk about the tools they use (Rabbit, anyone?). By treating it like any other normal, human function, a burden was lifted, even for those of us who were raised to be open about sex.
