OK, I have a little problem when I do wet jelqs . About a year ago, I got a large pimple on my penis and won't get into any details about that. But, it left kind of a scar and when I jelq is becomes purple and hurts just ever so slightly. I'm really not sure what to do. I feel like if I wait for it to heal, I'm not even sure that would do anything or stop it from happening when i started jelqs again.
