You know how some guys like big breasts for women and some like small ones?
Now if I were a woman I don't know how I felt about my breasts. Whether they be small? or big? or very very big? Or whether they be different sizes? This latter would be an advantage, cause I could have dated both types of guys and eventually ended up with one that couldn't make up his mind between big and small, so his only possible committed relationship could have been with a flexible woman; big when you want it big, small when you want it small!
