Girls, if your boyfriend...?

Well I know I would feel very hurt I have asked my boyfriend before if he found the others girls he slept with more attractive then me or if they were better at sex then me (he has casual sex 2 times before we met) and he said no that I was the most beautiful women he knew and great at sex. BUT if he told me otherwise I would break down crying and ask why he was even with me then. and get upset and question our whole relationship....The Megan Fox thing I would not take seriously tho
