My biggest problem with girls is that I have that nice/sweet attitude, and I can't seem to get rid of it. Girls are always like "aww" or "you're so sweet", and I'm tired of it. I think I used to perceive that as a good thing, back in around middle school, so I never really dropped those mannerisms so it stuck to me to this day (I'm 22).

What's the best way to eliminate this label I have? I'm not a "nice guy" in that I don't cater to every girl's whim. I think my personality just comes off as very kind (even other guys say how nice I am). What's the best way of getting that balance of kindness without being so sweet that it hurts my chances sexually?
