On the right side of my penis, there is a very sensitive spot, where I believe was cut poorly when I was circumcised. This spot tends to produce dry, smelly puss after some time. A couple days ago, it was badly bruised through rough masturbation. Hours later, I took a shower, and it hurt. The next day it was sore, but I masturbated again. The next morning there was a covering of puss over it, but it was not leaking. Can you help me...
