Wade. I am not a surgery guy, but from what you have said it would appear that you are doing well 4 months on from your surgery. Even with nerve sparing surgery there is still a lot of trauma caused in that area, so you have to allow things to heal. Although as Peter said, you should now be concentrating on what can be done regarding you ED issues. I tried the Viagra thing a few years back and found I had the same results as you, but my issues were being caused by depression at the time.
I would look at the fact that they are unable to find any cancer in your post surgery biopsy as a good thing. "No news is good news"
Doubting your treatment choice serves no purpose. You saw your doctors, gathered all the information and then pulled the trigger. After doing all that there should be no looking back.
NEVER think that your worries/concerns are too small for mentioning here. That is what this place is all about
. Sometimes it is good too share what is going on inside your head. No matter how small or embarrassing it may appear to you. I have not said this before, but last month when I went for my treatment my mind was in such a state that I put on odd socks. I never noticed, but the nurse at the hospital did!. Did I feel stupid at the time? Yes very stupid. In fact I felt so embarrassed that when I came home I left the grey surgery support stockings on LoL
All the very best to you. Please keep us posted with any updates. Even if your socks don't match
