From your experience, you know that being rough with your genitals leads to problems, so there's no point in warning you about that. What's done is done. It's interesting about what the urologist said, because you still see and feel damage. Do you usually wake up in the morning with an erection? If so, that is a good sign that your organs are working. If not, then more healing has to be done. Keep up your general health by not smoking, limiting alcohol, eating proper foods, and exercising to keep fit. Depending upon your situation, you may want to go to another urologist for a second opinion, if possible. Explain what you did and see what can medically be done to correct the damage.
Well shaboon , have you had a dopplar ultrasound , an MRI or any sort of imaging done? If not then I advise to do so
Like yardbull said if you awake with morning erections then it is a good sigh (NPT determines weather your erectile dysfunction is mental or physical)
and did you hear a snap or a pop or anything?
