Pretty smiles and nice eyes really do it for me. I have a lot of physical traits I like in women, but pretty eyes get me excited. If a girl has cute flirty eyes, or deep green eyes, that works its number on me. There are few things that work their number on me, but pretty eyes are definitely one of them.
All my friends think its hilarious, since nearly every girl I've hooked up with lately has green eyes. They'll joke about it, "I know this really cute girl for you but bad news, brown eyes."
