Circumcision healed


I will start off by saying, if you have anything rude to say or spam me with "pro-intact links" your comment will be deleted. My son is 4m old and was circumcised right after birth. They told us to not retract it while it healed. Well I just recently noticed that at the top of his penis, some of the skin healed back to the head. is this going to cause issues in the future..?
