The biggest turnoffs for me are personality based and pretty much the same as what Lil posted. As far as what will just kill the mood with me....... biting. I don't mind playful nibbling and if it accidentally is a little too hard that's nothing to worry about. Had one g/f who actually drew blood while performing oral on me and OMFG, I thought I was going to die. She also got way too agressive when in the nipple area. I honestly thought I was going to lose body parts to that woman. So rough stuff biting is out for me.
