Great post, Jen. You make some fabulous points. I particularly loved this from the article you referenced: Brilliant, funny, and powerful women are retreating from sex as never before, and if you don't believe it, take the curious case of Liz Lemon. The most complicated and intelligent woman in television comedy barely ever has sex...
I think the "sex is power" idea is true in the sense that owning your own sexuality is power. Once a woman has figured out what the game is, they can make their own rules. Regardless of the rules, she must stick to them. Knowing what you want (both in and out of the bedroom), THAT is truly empowering.
