The reality that women are stronger than men

Has it ever occur to you the mystery behind the inner most strength ladies possess whenever they are making love or having sexual intercourse, their ability to have a man ontop of them for a long period of time without complaining about the weight of the person marvels me,so I was talking to a friend of mine, a lady one day and i ask her this particular question and she responded that, actually when a guy is ontop of her he possess a lot of weight but immediately he insert his penis or dick inside of her that the person becomes so lite, so i was wondering the mechanism involved in that process and to understand the equilibrium constant of this equation. But i just concur and said that God is infinite in his knowledge and doing.
