My Sister is not concerned at all but I can't help but feel that she should get him checked out. He is six and has an enormous winky. It is about 6-7 inches long and thick (sorry TMI). He rubs himself to get hard and then it is HUGE (he runs around showing everyone). We all feel slightly embarrased as it is as big as a man's but she doesn't she anything strange.
Should I be concerned??
