Hmmm, not bad. Although you then run the risk of offending a skinny girl who really just wants to hear you say she's gorgeous. I'd strongly recommend saying 'no, your perfect'....if your spending forever on that topic you might want to get out before you go insane...lolz
You should really work on your self esteem though.
Its pretty amazing how much good a bit of self esteem can do for your life.
