Other than the sensitivity difference in my penis. The other things that I notice is when erect my penis feels harder on the right side as compared to the left side. Also at the time of injury I checked multiple times two things I felt are that the left testicle had shrinked but apparently the doctors and the ultrasound said everything was normal. Also I felt that the left testicle was quite colder than the right testicle. If u could explain this situation and give prescription that would be of great help. Thanks
