I had my first morning erection with the catheter in. Hard to believe but true. After the cath was removed I would have erection every morning like clock work. Boy I was very encouraged, then things slowed down after a couple of weeks. Now at 20 weeks I am just O.K. with out Viagra, better with Viagra and a constriction ring. Orgasms are sometimes nothing and others great.
My Doc said that this is becoming more and more common with nerve sparring DaVinci method. They dont have a name for it but its there is mounting (sorry) evidence that this is a rising (sorry) developement for which they are looking at. Hard (sorry) to find any statistics at this time.
