confront her

you must confront her, i would do it by 'accidently' catching her you can talk to her ab out it after that n explain to her that u didnt mind it because you love her and u kno she loves you and u kno that she is doing it just for the pleasure of his size in her and that its something you can not give her, a nd then you might even be able to sit in the room and watch them!
