I've been experiencing some issues after masturbating where I get small cuts on my foreskin, and it's becoming a bit of a concern. They tend to heal after a few days, but as soon as I masturbate again, the same thing happens. It's quite painful, and sometimes I can't even retract the foreskin because of the pain. I'm worried and wondering if this is something I should be concerned about or if there's anything I can do to prevent it. Could you provide some advice on what might be causing this and how to stop it from happening?
