Like Leviathan, I've always considered myself a top, even before I started having sex. When I watched porn when I was younger, I always got off by visualizing the guy getting fucked, his ass getting pounded, I never really concentrated on the cock. So I identified with the active partner. It wasn't until, when I was about 13 or 14, that a gay friend asked me online, when I came out to him, if I was a top or a bottom and I had to ask him what he meant. Upon explaining, I said top.
It's strange, because when I was REALLY young, like 11-12, I hadn't discovered masturbation yet, but I knew I was gay. But I just wasn't really aware of my dick or what an orgasm was. For some reason, I assumed that gay men don't jerk off. So I would finger myself and hit my prostate, and to me, that was masturbating. I think I was a bit confused because of the societal stereotype that all gay men are passive bottoms. But when I discovered jerking off, I liked that a LOT more.
But regardless of that strange period, I've always been way more into guys' butts than their cocks. Again, even before masturbating, I was always staring at my friends' asses, pressing up against them, sniffing them, touching when I could. I just love ass. And asshole.
I identify very strongly as a top, but my boyfriend is also a top so we switch every once in a while. For the most part we just don't have that much anal sex. But if we do, we sort of take turns. I like it more than he does. He just thinks it hurts and doesn't get any pleasure from it. I think it hurts but in a good way... and I want to come after a few minutes, can't do it for very long. He has a really big dick though. So I guess I'm kind of versa-top, but I only bottom for him since we're both tops.
Aside from sex, I'm generally just really dominant and aggressive. I like dominating other guys and emasculating them a bit. I think it makes me feel more evened out.
