OK, no more playing devil's advocate. Mrs HD can stand on her own!
I am confused. Is the issue just that HD wants MsHD to spread her legs for him once a week?
No, of course it is more than that... to him. But as Corri says, it is just a task for her, and the bottom line, after all the arguing and rationalization, is that she won't open her legs, and no amount of logic is going to make her do that.
