GBINAB -- thanks for the encouragement. I guess it's a good sign that we're in here worrying about ED -- there could be much more serious things to worry about.
I know that it's somewhere between a slim chance and no chance that I will ever have natural erections again. But nerves do grow back given time, and I'll do my best to encourage that -- and have fun trying. Nerve regrowth is a slow process and it's important that we don't give up too soon -- let us all be glad and celebrate each little improvement we can gain.
I haven't lost any blood supply to the penis -- it's just that the nerves turning on my tap have a big gap in them. I opted for non-nerve-sparing because of the aggressive nature of my cancer (Gleason 9, since downgraded to 8), and didn't even ask for the nerve graft. There seem to be doubts about its effectiveness in any case.
I did some math. Before the operation I had sex about twice a week. This required that I have an erection for a total of 1.68 hours during the week. If you think that I'm cooking the figures here, you're right! As a percentage of my week, that is just one percent! I can still have sex, still twice a week if I'm lucky, but now I need artificial aids. So that one percent is not completely lost, but the quality has changed -- and sometimes there are flops -- in both senses of the word! But my overall quality of life has changed very little.
So for anybody else sweating over ED, do your own sums, and figure out what percentage of your week you actually need an erection.
