FWIW, I really do feel you are under so much stress. You are feeling physical pain in the one area that has brought you the most comfort. It really is a lot to deal with.
Drop the desire issue for now and wait until you are feeling better after the surgery to re-address it all here. I can tell you that most long term wives have that Mrs. Roper feeling from time to time, and it does suck. But right now you just have to concentrate on getting well.
Sending you lottsa extra chocolately hot chocolate ( Mr. HP is not the only one in the house with a sweet tooth, I bet).
