I'm not or barely ever sexually attracted to people. I think. I don't actually know what it would feel like, so for all I know, I might and just not know it. There may have been one time recently when I was sexually attracted to someone, but that was literally only once for a bit. So I guess that would make me asexual or gray-asexual? Except I like sex which means that most people would not consider me asexual because they don't understand how I could like sex without being sexually attracted to the person. So I guess I'm not.
I don't really care who I have sex with. Which, according to some people, would make me pansexual. Except I'm not pansexual since I'm not sexually attracted to everyone (or anyone). While I understand that it refers to genders and not numbers, I'm still not entirely comfortable calling myself that. This may also be partially because I got really sick of hearing pansexual "allies" claim to be attracted to "men, women, and ->-bleeped-<-s," hearing them talk down to bisexuals despite the fact that most bisexuals mean exactly the same thing just with less offensive slurs, and having them argue with my boyfriend about his sexuality because they do not see me as a man.
I call myself bisexual because, as I said, I really don't care who I have sex with (as long as it's not forced and/or pressured onto me) and I consider it to mean the same as pansexual.
I've only ever had sex with men and generally prefer them for dysphoria reasons and feeling like I'm able to click with them better. (I have no idea why.) So I sometimes call myself gay and many people assume I'm gay. This probably isn't fair to guys who genuinely are 100% gay, but it's difficult not to feel like the label at least partially fits when I've exclusively slept with guys.
In short, anything that isn't straight or lesbian.
