I tend to sweat a lot all over in the warmer weather, and need to drink copious amounts of fluids to stay hydrated. When I work out, I sweat a lot in the groin/buttocks area and I need to shower and keep this area very dry after workouts.
Like you, I was worried quite a bit about the possibility of impotence as this was a risk, albeit slight, that my surgeon prominently mentioned when we went over the informed consent issues. He strongly recommended I bank my sperm (I didn't). I had my J Pouch surgery done in 1992 and because everyone was scared crapless about AIDS at that time, I was actually affirmatively required by the hospital to donate a large amount of my own blood in the weeks prior to surgery (in case I needed a transfusion during surgery - and I think I did). Several years earlier, tennis legend Arthur Ashe had contracted, and later died of AIDS after receiving AIDS-tainted blood during a transfusion while undergoing heart surgery.
My recollection is that I had an erection very soon after my urinary catheter was removed and it was a great relief when that occurred. You might say it was the happiest erection of my life, although since I was in a hospital bed at the time, there was not much I could do with it.
