Besides the "typical" things, for some reason I often find Goth and Punk chicks pretty hot. And pink hair. Or dark hair with colored strips. Yeah, I think a big part of that is what they do with their hair. I also really like it when girls wear clothing that is both feminine, a little bit sexy, and classy at the same time. Too bad t-shirts and things like that are becoming common these days. But not counting physical, I like a girl who can be sexually aggressive. There isn't much more that gets you going better than that.
