Seriously guy, the lady asked. This is the eternal social contract. You have a surplus of available labor and she has a surplus of child bearing capability in which you are severely lacking. You invest your labor, she invests her gracious presence, you get laid or you don't but you can't complain that the opportunity was never presented to you. Make her pick up the other end of the board and get on with it. You can't win if you don't play.
