Personally, I like guys who are short and cute, but confident, slightly manly, scawny but fit (not real muscly at all), and not very hairy, and any race but white. Pretty much the big summary is I think white guys are ugly for the most part, sums it up well. My personality type is pretty alternative, so I tend to like guys who aren't preppy, sportsy, or normal, but a bit more around the edge. Most of all, they plain out have to have the specific body parts that match with a few strange fetishes of mine (specific feet, hands, ect ect) or else I can't find interest in them.
I pretty much would like a strange mixture between Justin Bieber, Shia Labouf, and Taylor Lautner, just speaking of celebrity examples. I absolutely would not touch someone who looked like Robert Pattison, he looks like what would happen if Quentin Tarantino mated with a foot! (Which is a fetish of Tarantino's, believe it or not...)
Also, personality wise, I tend to need someone who's been through a lot, like abuse and medical problems, or else things get to a point where I want to express my experienced, serious side, and some spoiled brat can't stand it. However, it gets to be a problem there too, because I'm enough grumpy to go around, I want someone who's always happy around me, someone who doesn't get mad about everything. The first person I fell in love with happened to go through a fraction of what I've been through, and it was enough to make him a grumpy, picky prick. The second person I fell in love with had never been through anything horrid, but was a heck of a ton nicer and happier. Go figure.
