Do men in general treat women that are thinner and better looking differently from one that is larger heavier?

Men that act like that usually have self-esteem problems and small genitals. So, don't worry about guys like that. Also, thin gorgeous girls think too highly of themselves, having them come off as self-centered. Men do not like girls like that. (Most) Guys do not like girls like that and will only use them for sexual intercourse. However, the gentlemen that come after the bigger ladies with the nice personality will usually be genuine and sweet. Those are the ones to keep around. Good Luck!!
