There are many "Bigger" girls out there that I will say, pull off the look quite well. I'd rather date a "chubbier" girl, as oppossed to a skinny skinny girl.
I don't know, but maybe some of you like these girls because you feel that because they don't have the supermodel looks, they're bound to be nicer and/or give the chance to date you, ultimately boosting your confidence?
I have one thing to say to chubby girls. If you love the way you are, then that's great! A guy will eventually see this and love it. I dated a chubby girl once and all she did the entire time was complain about how fat she was, which was a major turn off when. If she said good things about herself it would have been sexy. If you are chubby and hate it, then the weight needs to come off! Your confidence will not change unless you physically change yourself into the person you aspire to be.
