Hello. I have a question about the glans on my penis. Early this morning, I was a bit intoxicated, and decided to use a high-powered neck massager on my penis.
I was using it while erected until I ejaculated. I went to the bathroom soon after, and noticed my penis had (what looks like) a bright red shiny blotch of skin. It looks like a rash. As of now, I can't tell if the rash is painful because of my anxiety. I am 28 years-old, sexually active. My previous sexual encounter was with a girl who just performed unprotected oral in early January.
Can this be broken blood vessels on my penis, or some sort of developing STD rash. It's bright red, and somewhat shiny. It does feel painful if I touch it.
