l masturbated last night and now on my penis when l pull back the skin theres a part of my penis that has 2 seperate little red spots (i think it got like ripped skin a little) and on the penis skin that l pull back it has those 2 red spots too and the same space away and they go together with the other 2 when l put it back what happened?

Nothing to worry about.
You were a little rough.
Use a lubricant in the future.

You were probally too dry before you started, try a lubricant that should sort it, but be gentle until the sores heal again.

just let it rest for a few days.
