Update: What’s on my boyfriend’s penis? TMI

My boyfriend started getting a rash on his penis . He says it’s really itchy and swollen . Anyone know what kind of rash it can be ?

Update: it was poison oak ! We went out hiking and I guess he touched poison oak and went to the bathroom and forgot to was his hands before he peed 🤦🏻‍♀️ . He also started getting rashes on other parts of his body
