Welcome, Many of us here have had the RRP, thats pro talk for Robotic Rad.. Prost.... There is much to be learned here about
leakage and ED. heck, I have only been here for about
6 months and now I have both of these problems, but most likely my situation was from the surgery.
A lot of patients get sent to physical therapy for plevic floor muscle strengthening and many are helped by this. You didn't say if you had done this but it is something you might want to consider. It can't hurt?
You will find there is tons of discussion on how to deal with ED. Do some site searchs and you can see what others who have been this way have done.
Like you, I had a good experience with the surgery as far as pain and recovery.
