Apparently the women have no say in this. Maybe this "cretin" you speak of should have woken his girlfriend up just to try to bang her? That'll go over well.
I get what you're saying but this post is pretty ridiculous. Like Sojoe said, these people are regular everyday people. They fuck when they want and watch TV and do shit on the computer whenever they want, like anybody else in a relationship.
Also when the women want sex, they can go after it too. Why do you just call the guys idiots and cretins? You must be very young or very inexperienced.
