Man you can try the CLA if you want to, but I'm not sure how much help it will be. Time may help as well. But I must tell a story.
I was recently swimming in a natural body of water with a buddy. I don't pull back generally when I swim, especially since I don't want to expose my head or inner foreskin to bacteria, protozoa, fungi, and other microbes in natural bodies of water. So swimming for me was/is fine. But while drying off and changing, my buddy tells me a story, perhaps as an explanation of why he swam in his boxerbriefs and not his swimsuit. He said swimming in a regular swimsuit or board shorts caused quite a bit of friction on his dick, specifically his head. Normal underwear he changed into continued to ihflame his head. I didn't pry or bring up the topic, but I did clearly notice that my buddy is definitely circumcised. He said that the pain/irritation was so bad that he asked his friends mom (he was crashing at a buddy's house) to go get him some performance underwear (I'm guessing to minimize friction or for sleek smooth fabric) so he wouldn't hurt himself any worse. (And she did go get him some. You might try this too.)
I thought about saying to my buddy something like: Bro I've never had that problem ever, cause I have foreskin protecting my head from all that friction. Or maybe dude you wouldn't have that problem if your parents let you keep your foreskin. But I chose not to say these things, as I don't want to potentially hurt my friend's feelings or make him think I'm looking down on his body or possibly hurt our friendship. Maybe one day the topic of intact/circumcised dicks will come up, but I think not yet. I value friendships, especially close buddies, and it's not right to hurt your friends.
But guys theres one more reason we're here on pulledback - Though we may in many instances like being pulled back, when we come on situations where we do want protection, we are driving a convertible, and can pull the skin over the head, and then slog through the swamp protected. And guys if you never get dirty camping, hiking through rivers, swimming, wrestling (mud optional but why not?), you are missing out. It's never too late to get your shoes dirty, and they (and you) generally are washable.
