Most Helpful Guy
Top) Desperation. I think this is #1 turn off.
2) Lack of confidence. When comes to dating, lack of sexual confidence (which includes body image confidence) is another turn off.
3) Arrogance. This has nothing to do with being Confident. Such arrogance boasts of things the person lacks and yet make seem as if the person is superior. A major turn off.
There are others, but not as important and could be excused if there are attractive personalities.
