Indeed. To me, sex is the ultimate intimacy and I can't really imagine doing it on a casual basis, nor do I think I'd enjoy that very much. Sex as an expression of deep commitment to another person is one of the best experiences two people can share. But I can empathize with the subject in the OP. After several painful breakups and the ultimate, a failed marriage, I'm done with it. I don't care if I ever have sex again. I'm not getting back on that roller coaster, the pleasure is not worth the pain.
