A turn-off for me is when a woman takes herself so seriously she can't laugh at herself...also dealing with their various psychological problems and them blaming the guy for everything wrong in their lives yet they can never admit their own mistakes/failures..
and of course a woman who uses teeth on a blowjob...WOW!..thats a serious turn -off..oh and another thing...a woman who refuses to blow you PERIOD because they think its dirty..LOL
