Thanks for gathering this information. One thing that was not clear to me was the relationship between pills, pumps, shots and the actual sexual performance. As an example, I am Not able to get any erection with or without pills, but I always get a full erection with a bi-mix shot. So I answered that I was ready to go everytime. Without the shot I get NO erection at all.
I am not entirely sure how my doctor scores that one, but to me it is 100% failure. The only way I reverse that failure is with shots. I don't think your survey related that information correctly. Maybe you should have first asked if an erection was possible without shots, pills or pump. That would be my definition of success. What do you think?
