I think it's safe to call myself asexual. I do not understand lust at all, but it's symbolic to me. I've had sex a couple times and didn't really care for the act of it, but who I was with was what counted. If I have feelings for someone, it'll be my motivation and a way to personally feel connected to them. (Although, I'm positive the others don't see it that way. : /)
I take notice of females' physical appearances quite often (sometimes mens') and I think about sex in general quite often. But it's never a "Man, I want to do that person!" type of thing.
I don't particularly care for sex in a self-involved way, because the thought of me with someone grosses me out, but I'll read dirty fanfiction and look at lewd fanart of fanmade pairings I like, but it's pretty much for observational purposes.
But really though, I don't understand how so many people can just give their skin so easily. I'm sure some of it has to do with being extremely self-conscious, but even then, being "desired" makes me confused and disgusted. I don't like the psychology of most straight guys.. It's not flattering at all to be pursued because I'm "pretty" or whatever. : / I know that a ton of guys don't bother getting to know a girl if she isn't attractive. That bugs the crap out of me.
