How is it going now, after a couple of months? I think it was great that you were onto it so early in your process. My surgeon (surgery in Feb) was really unhelpful and I had to find resources myself, now getting great help from a pelvic floor specialist.
I am nearly six months post surgery, and three months since I got a pump, and celebrating at last reaching the point where my wife and I were able to have penetrative sex again (with the help of the pump and ring). It is still more of a promise than a reality - I find the erection easily fades still in spite of the ring. But it feels good to be connected again.
