Even though you may not be giving your son(s) their baths anymore, you would be recognizing if the penis was giving any one of them trouble. They'd be grabbing themselves or seeming to be really itchy or fidgeting a lot with the front of their pants. Perhaps not directly in public, but being a mom, you'd be noticing it because moms have 4,000 eyes and those are the ones in the front of their heads. For ex., when my stepson from my first marriage was about 10, he started grabbing himself when he thought nobody was looking and we finally found out that his circumcision had actually been botched and he had adhesions which did not cause him any problems until he was that old ... causing him to have to get "redone" (Youch!)
I wonder if the original pediatrician (I'm assuming you didn't go back to this guy) also suggests creams, "skinning", and circumcision for the clitoral hood on girls. It's quite obvious that this dude didn't know much about the body part he was talking about.
You can get some very good info as far as to what a normal foreskin looks and acts like from the writings of Dr. Paul Fleiss. Try: www.foreskin.org/fleiss.htm or www.infocirc.org or www.mothering.com. All of those resources will give you good information on foreskin retraction and care of the intact penis. Hope that helps.
