The term I've seen on the internet is solosexual, someone who would rather masturbate than have sex. That's me. Basically the only sexual pleasure I have any interest in at all is my own. I'm 41 and have never had sex and have never really been interested in doing so, except as a "macho" thing, it would make me feel attractive that a woman wanted to have sex with me. But other than that I just want to get off and I can do that by myself. Never been much interested by women's vaginas for some reason. I've said that the closest thing to intercourse I would be interested in is a footjob. Haven't had one yet, maybe some day when I'm willing and able to spend that much money on a prostitute. Can't catch anything from a prostitute's feet, right?
By the way, I looked up asexual and it means lack of sexual attraction to anyone. So you may not want to have intercourse with women, but you want to do something to them, so you're not asexual.
