There's nothing wrong with talking to strangers, while they don't know you personally, at least you know there's no preconceptions that might guide their words. That said, as for having it be different, maybe it is something you need to talk about to somebody you know personally. I would encourage you to try to change it if that's what you want, it's better to try something if you feel you might regret not doing so. I have never been a person to want to have a one night stand as well. I don't have any problems with casual sex, but I prefer for there to be some deeper meaning behind it. There are many people that feel the same way you do, probably as many as are for casual sex and one night stands.
Thanks. Fortunately I have a few friends I feel comfortable talking about it with, and it does feel good to put it in words, both to people I know and that I don't. Not being a psychologist or anything of the like, I do wonder how our past choices and behaviors affect our personalities or behaviors now - in a way I'm trying to see if there are things I've done that have, in their own small ways, influenced my lack of interest in sex and romance. In general I don't think it's a problem to live without those two, but I find the idea of sex and romance to be appealing, even if I don't outwardly want it. It's like enjoying an apple, but never being hungry for one - only I've never had an apple, in this case. For people who have had sex, I wonder how their fantasies of and outlook on sex has changed. It's hard (for me) to really fantasize about a shared experience when I don't know what that'd be like. For others it might be easy, even if what we imagine sex is like before having it is totally different than what it's actually like. Hell if I know. These types of questions are harder for me to bring up in person, I suppose because they have a taboo nature about them, where it's easier to talk about on anonymously on the internet.
