My son is 4 1/2. He retracted himself maybe 9-12 months ago. At that point I talked with him about retracting in the tub to get clean everywhere, but I admit I don't always sit there every second when he is in the tub, and I can't say how consistent he is with doing that. I've also talked with him about retracting when he pees, but he usually does NOT do that. I have not fretted over it because I figure for the first 4 years of his life he peed with the foreskin down so it's probably not a big deal...
Yesterday he came up to me after going to the toilet and said that his penis hurt. He pulled back his foreskin to show me (after telling me to not touch cuz it hurts), and about half of the head of his penis is dark red. I don't see any bleeding or places that look like a rash or a cut/scrape/etc, just part of his penis is definitely a much darker red than the rest of it. He says it is very sore, and every time he has gone to the bathroom in the last day and a half. It doesn't look different from the rest of his penis except for the color--it's not dried out, i can't see a line at the edge of the color change--just part of his penis is darker and he says it hurts.
I have no idea what this is or what might have caused it. Might it be an infection?
Is there something I could/should do or put on it? He's clearly upset by the pain (he is in a dramatic stage, so I don't know how severe the pain really is--he hasn't been crying over it, but he definitely doesn't want me to touch either. He says it hurts whether the penis is in or out and even when it's in his clothes, but he has only mentioned it to me after going to the toilet.
Do I need to make sure he washes better, or retracts when peeing? Forgive me, I don't really know my way around an intact penis!!
