Ya know I'm not real sure what this is.. BUT, I know excatly what your talking about because I knew a guy who had this. He would put lotion on it and it would go away for a while, then come back. Some suggestions though: the soap you use? You could be allerigic. BUT, I would go to the Doctor anyway. Keep us updated bc I'm curious about this!
I have a lot of extra foreskin too. but what I do is every time I have to #1 I always use a wet wipe at home and carry them when I leave home. and sometimes during the day I will go to the bathroom to just use a wet wipe to clean it and I keep it clean. Have you ever tried this.
