I don't consider myself as "attractive", I hear that I'm cute. The most compliment I've got from opposite gender is my dark brown "button" eyes.
As what I think is attractive... OMG I don't know! I find Jo very attractive but he wasn't that the night I met him. He was wearing work clothes in a nightclub, ewww. But he was really nice and I noticed that he has a really warm personality.
So I've to say the way you talk and personality is a big plus.
PS. I love little beer bellys... It's nive to hug LOL
