I'm like you. Looks really don't matter all that much to me; personality is far more important. I also find it hard to be physically attracted to someone if I'm not mentally/emotionally attracted as well. However, I find that I'm usually attracted to guys with dark hair. Eye color doesn't matter so much, but I love the dark hair. I also love for them to be taller than me (doesn't take much, by the way) and I like 'em skinny. I really don't have much of a preference, but these are the kind of guys I'm typically attracted to.
As for personality, I usually like someone outgoing because I'm introverted. Definitely someone who can make me laugh, and someone I can have fun with. I'm kind of "one of the guys" and have a pretty good amount of guy friends, so I also need someone who can handle that and not get jealous. I love light-hearted, easygoing guys with a good sense of humor. I prefer someone who can have a meaningful conversation with me, someone who thinks and feels as deeply as I do, but it's not necessary, as long as they understand that I'm like that.
