I think you should enjoy your life whether there is a another person in it or not.

I can understand not wanting sex for personal reasons, but I am worried that you are allowing a fear primarily of the unknown to limit your options.

I don't want to seem insensitive but I do wonder if you are over-looking another possibility. Are you sexually attracted to men? Have you allowed yourself to explore the possibility that you may be more attracted to females?

If you were interested in dating, I think you could find someone to meet you needs. I haven't looked but I would almost bet there are dating sites or organizations for people who prefer not to or physically can't have sex.
