Balanitis?: Maybe balanitis (inflammation of the glans penis, esp. if uncircumcised.) It sounds like you might have tested yourself, e.g. through a lab you found on line. You need to be professionally examined to determine what is wrong and how best to treat it. The wrong treatment (e.g. bacitracin if it's a fungal infection) could make things worse.
