She dreams of love – he dreams of her nice butt!
She believes her ass is fat – he believes he is Adonis…
The difference in self-image between the genders is probably caused by this fact:
Women can talk to people of the opposite sex without having to picture them naked…!
And somewhat related:
A woman needs to know but one man well to understand all men;
whereas a man may know all women – and not understand one of them.
