hi, I am so much worried, after I had sex with my wife, my wife use to play with her clitoris during sex, and some times her nail fingers may hit my penis head, but when the wound place repaired itself, it leaves a 2mm white smooth dry bulb-like skin (the white spot is much bigger the scratched area on the head skin), I am afraid if I have a dangerous, disease, as I did not have this situation before one year, so please I need your help
