When I was 15, I got my right testicle removed because of an injury. That was actually less than a year ago. I could masterbate after the surgery, but the erection never lasted long. Now I can't get sn erection at all and it pisses me off, that I can't masterbate, but everybody else is enjoying erections. I never masterbated before the surgery, but I think having 1 testicle made me unable to maintain an erection, is ThaT true?
