Most women want to marry a man that is just as tall or taller than them. Very rarely do they say they don't mind someone shorter. Even if he is shorter, it is only slightly less.
This is a case of where there are physical requirements in finding a mate.
Nobody blinks an eye when a girl says that. Almost every tall girl I know finally married someone taller than them. I think maybe I should have my own requirement, just as tall women want guys taller than them, I should require my wife to be slimmer than me or have bigger boobs than mine.
But seriously, there is this mistaken belief that physical appearances don't make a difference.
I think it does. In acting, modelling, stewarding in an airline, appearances do matter.
