I guess the first question is, do you actually want sex, or do you just think you ought to want it?

There are a number of asexual people who post here occasionally. (I'm afraid I wasn't very supportive when I met them last, but I've done some growing since then...) They would tell you that society puts great pressure on people to be sexual. But is possible to have a life partnership with someone without any sex at all. Would that meet your needs?
