I can only speak for myself of course, but,....
BEFORE surgery, I was able to become aroused if my wife put on perfume. All I needed was a passing glance and it was "lock the doors and take the phone off the hook" time.
AFTER surgery(nerve sparing), there was nothing at all, Nada. I tried pumps, pills and shots.....Bupkass.
It took 4 months for the full strength Viagra to have any effect at all. I was never sure if I was able to perform.
It was about a 10 month timeframe before I was confident that Viagra would work every time. I must say that my understanding wife would not let on that she was disappointed when I experienced failure. This was very important to my psyche as I would be willing to try again.
I can finally say that, at 18 months, I am pretty pleased with my progress. And so is my wife. There have been times when I have NOT needed the Magic Pill. But, I still use it if I want to be sure. Although, when I take the Viagra, I usually have a raging hot flash about 45 minutes after taking it. My face gets flush and everyone comments that I look as if I was outdoors that day. I hope this doesn't give away the secret or my wife will be embaressed beyond all belief.
So, thats my story, and I'm sticking with it!
