She probably doesn't want to do it because you keep asking her for sex, which is making her think that she can have sex whenever she wants it because she knows you will give it to her when she wants it.

And knowing you can have sex whenever you want it is a good feeling and she doesn't need to do it all the time.


So my advice would be to lay off sex for a while. Maybe a week or so. Don't meantion it at all. And the first time she asks for it, don't give in right away.

Turn the tables on her and make her start asking.
