hi if this is the right side this side rests against your underwear seems like it could something used when being washed try going commando for a couple of weeks to see if it goes if it does you now know the answer its either a detergent of fabric softener. good luck
itching/burning feeling on the side of my penis only one side. not getting worst and it comes and goes. there's just an irritation on the side of my penis it doesn't always cause discomfort but when it does itching it relieves it for a while but then it just makes me want to continuously scratch at it until it breaks skin every so slightly
