I agree with Laura1229, take him to an intact friendly doctor, one who won't retract, as that can cause damage.
It could just be diaper rash, just keep it clean at diaper changes, use some diaper rash cream and keep an eye on him. If he seems not really bothered by it, and it goes away by itself, he should be fine. But like she said, if it gets worse or he gets sick, take him to a doc.
