My grandson,is constantly itching at his penis.I first thought he had to go use the wasroom.But he always says No that it is very itchy? Is there something wrong?

If he is uncircumsized the problem may be that no one has ever pulled back his foreskin to clean around it. Now is the time to teach him that this has to be done. He could very well have a type of diaper rash around his foreskin area that is bothering him. Take a look at that area while teaching him it has to be pulled back and cleaned.

If he is circumcised, well it could still be an irriation from a form of rash.

Just as grown men, many can get a slight infection. Have anyone looked at it ? Have you tried anti fungal creams ?
