burning on the outside? if so. this is just some chafing or raw skin. get yourself a penis health creme called man1 man oil and use it every day. it will repair your skin and keep it that way too. it's a great product. totally safe too. good luck.
burning testicles but no burning urine or sensitivity on head of penis. no pain in head of penis nor have any burning when urinating and no rash of any kind just burning testicles
