Why there is only ONE rule in the world of romance which is “Make the woman happy”??

Why there is no "MAKE THE MAN HAPPY" too?!

Women want to be equal to men when it comes to their rights but when it comes to their dues they remember they are women and want only to be treated as the soft romantic species!!

WOMEN!!! what a selfish creature!!
but, as they say we can not live with them and cant live without them :) :)
