I don't know,a turn-off for me as far as appearance would be the way he's dressed,bad hygiene,a guy with no ass would definately turn me off.His teeth,and believe it or not,the way he moves his lips when he talks.I'm pretty complex,but I'm learning as I get older to not pay attention to outward appearance so much.I think it's better to focus on his personality and actions.I mean,if he farted or picked his nose on the first date,I'd run far away.But if he had a few flaws in his appearance,that can be corrected.But overall,a guy that lacks intelligence and doesn't conversate very well,would be my ultimate pet peeve.
