I also dealt with this with my son. His got to the point that it started to look infected so I took him in. Turns out that just like the other posters described the skin just needed to be pulled completely back. I was not very good at doing it because I didn't want to hurt him, but try to pull it back all the way until you can see the little ridge. Clean it every diaper change. The doctor said most of the time you would only need to clean it like that once in awhile, but for him I was supposed to do it every diaper change. And still for that first year every time we had a doctor appointment the doctor would have to pull it back himself because I hadn't done it all the way. That always hurt him. So I encourage you to do your best at getting it pulled back now and keeping it pulled back to avoid that. He is two now and it is not really a problem. I still try to pull it back to clean it but it isn't sticking any more. My next son had no problems at all with his circumcision, so I think it is just some that do. I hope that helps.
