First time poster. Have had a strange rash pop up on my penis head and shaft the last few weeks. Tried searching for similar pictures and haven't really found anything specific. The larger one started off small just like the other picture and just kept growing. Should I head to the doctor or can anyone point me in the right direction as to what this could be?
Eczema?
Looks like a friction burn or possibly irritation from something, maybe a new lube?
