Recently, about 2 days ago, I had masturbated one night, and noticed the next morning in the shower the head of my penis had a red mark. This has happened to me before but it was almost 3 years ago. I am 18 years old, not circumcised, and I masturbate by using the foreskin and rubbing it against my head. The incident 3 years ago healed up in about 2-3 days.
I read up on "Red Penis" after google'ing a bunch of stuff and it was a battle between articles and answers to questions to do two things:
1: Immediately go see a doctor or urologist
2: Let it heal, wash it, apply [insert name here] (usually Man1 Man Oil) cream, etc.
I personally don't know what to do. It was slightly inflamed yesterday, then this morning the inflammation disappeared, and now it is slightly inflamed again but it does seem like a smaller area now. I haven't masturbated since and have tried my best to keep any urine away from the rash.
