Dogs can definitely do this as part of normal grooming behavior, or maybe a bit excessively sometimes. It's also possible that something is irritating him down there. This could be something like an infection, allergies, or impacted anal sacs. It's a good idea to have a vet check him for any medical problems leading to the excessive licking. It's definitely possible that there is a reason for this, which can be corrected. I hope that helps.
