-The spotted Leopard print tattoos some females get. That's a no go.
-Boobs :P okay I'm kidding. So long she has boobs I'm good.
That's about it that I can think of. I like so many different kinds of looks and personalities.1

There was a guy in my school who was looking weird. Almostly everything in his appearance was a turn off to me, from his haircut to his clothes. Almost every day wearing the same clothes, hunched shoulders when sitting, not talkative, not many friends. Everything was a turn off to me. But after a while i got to know him better and fell in love :) Surprisingly every turn off became turn on.
So i dont believe in turn offs and ons :D everything depends on personality1
