If I'm fighting for the possibility of having a kind of desire and possibility, that right now is not too likely, it gives me a different kind of engagement with the future, than if I say, "sex doesn't matter; it's private."
I think desire gives us - imagination - as well as actually often we pay a terrible price for it. Women are punished around their sexuality and perceived to be immoral if they practice a certain kind of promiscuous sexuality. It's a very different thing still if you're a guy, if you're a woman and you're straight.
