If I am checking for attractiveness upon first glance, the first thing I look at is the face. Next comes their demeanor- are they approachable. A big turn off for me is when a guy just looks mad or like he wants to come off as a bad-ass. A smile is a nice addition and often pleasant surprise. However, for me the meaningful attraction comes later, once you get to know the guy. My questions are always: Do they listen well? Are they judgmental (turn off)? Are they open minded? Are they friendly? Do they have a good sense of humor? are they intelligent? Are they the jealous type? Are they trustworthy. well I guess I could go on and on with this one, but I will leave it there.
