Re: A ? for mamas with intact sons
If you go to the case against circumcison forum on mothering there is a sticky at the top on this subject. If that doesn't asnwer your question all the knowledgeable people there can.
To me it sounds like irritation from something. If your son were circ'd he probably would have irritated glans.
If it's not causing him pain, it probably is nothing to worry about. And you shouldn't pull the foreskin back at all, not even to apply the anti-fungal, just do it on the ouside and around the opening. Pulling it back, even a little bit, can cause small tears which could result in scar tissue.
