One. This is a dishonest power play, and every woman knows it. The second she's single again, she is not going to go to her next potential boyfriend or husband and tell him she doesn't want to have sex. That's never going to happen. Two. He is going to keep up with all the things he agreed to, but now she has withdrawn. So he has to jump through hoops to get back to what he had before. This is inherently and patently unfair. Three. The answer from feminist women and psychologists or marriage counselors is that he should approach her differently and do more. This is basically someone saying, now that I know that you are going to listen and do what I want, I'm going to make you jump through more and more hoops to get back to what you are. Four. I have seen this happen in real life, and you'll notice that very few times do you hear the person report, oh wow, I did that and everything magically got better forever. No. Now it's a constant need to jump through hoops and kiss her ass in order to just get what she gave you in the beginning.
