Two months ago I had unprotected sex. Several days later I began to notice some irregularity in the skin around the head of my penis. I'm still unsure how to describe it. The skin is smooth to the touch but appears to have a rigid or scaly texture. When erected very tiny red bumps become visible in this area, but can not be seen otherwise. There is no pain, itching, pus, etc. I've seen one doctor already who didn't think it was anything to worry about, but I am still uncertain. My partner says that she was tested before and after we were together and has no stds. Any idea what it could be, or am I overreacting?
