Because I guess that's just what I might be.
So, I'm 19, female, and I guess I'm potentially bi, meaning that I can find both women's and men's appearance appealing. I had two or three mild crushes when I was between 8 and 12 and then when I was 13 I kinda fell in love with a girl from my class. Yeah turned out she felt the same but as she was kinda mentally.. unstable we never got together. I was sad for a while but quickly got over it.
Two years later I had something between a crush and love for a guy, also in my class. He hit on me a few times but since I couldn't decide whether or not I actually loved him I didn't really react to it.
So the few times I felt close to something like love it was really unstable (burning desire today, disinterest tomorrow) and didn't last long, but most importantly it didn't come with the wish for a relationship. I feel kind of constricted and annoyed by other people's emotions, so at best I would have settled for something like friends with benefits, if there wasn't my sexual disinterest
Which manifests in a way that I can feel sexually attracted by people, but I'd never really consider "doing the deed" with them. I masturbate since I'm 8 (is that very early? Feels like it) and I guess my libido is essentially normal or a little weaker (1-3 times per week), and I don't have trouble climaxing either (in fact I only need like, 10 seconds). I have noticed, however, that I can only get off on friction, not penetration (man, sure feels weird to talk about this), that doesn't do anything for me.
Yeah so to summarize, I had a few weak crushes (and then nothing, for 3 years now) and no real desire for a relationship. And sex for me is something you do alone once in a while to satisfy a need, almost like eating or drinking, just because it's a part of life- I don't see it in any kind of romantic light.
Could I be aromantic/asexual? I've taken a few online tests but the problem is that most assume that you've already had sex...
EDIT: I just did another test and the result describes me PERFECTLY:
Self-Sexual
You make sex yours!
You may not hear this one very often, but it's an interesting branch of asexuality.
It looks like you quite enjoy sex...with yourself. This is by no means a bad thing, though. You know what turns you on and you don't need help from anyone. You may be an asexual fetishist, demisexual, asexual, romantic-asexual, or aromantic asexual, but either way, you make the walls shake with your solo acts.
You do not feel the need to have sex with another person. You most likely feel no sexual attraction at all for other people. You probably feel a much stronger sexual attraction toward erotica, images, art, stories, hentai, and your very own creative sexy mind. Your sex is not to be shared and you feel annoyed, uncomfortable, or apathetic when someone barges in on your parade.
Sex is a big part of your life, but not when it's intercourse with another person. You are independent, intelligent, and know what's needed to get the job done."
