I have hidden penis. urination causes "burn" on genitals & upper thighs. can you suggest ointment to deal with urine burn/ thanks richard?

Do you have rashes on your scrotum and groin areas which are burning with urine? If yes, you need to see doctor for cream or ointment to treat those rashes. If you do not have rashes, it is uncommon for urine to irritate the skin that much but you can try OTC Lidocaine 5% ointment and avoid too concentrated urine, i.e. your fluid intake should be adequate.

you can use vaseline or any diaper rash ointment to protect the skin. but I suggest you see a Urologist to see if there is an easy or simple way to treat the "Hidden Penis" to solve the problem
