How Should Penis Pain With Scabbing And Fluid Be Treated?

Hi, may I answer your health queries right now ? Please type your query here... About a month and a half ago my girlfriend and I were having sec when she scratched right under the tip of my penis it (circumsized) it hurt but I kept going and the next day it scabbed over but we kept doing it and it would hurt pretty bad which is understandable. Iv been gone for a month and it went away in about two weeks but just recently it came back I might have scratched it on a tube because I'm in the lake a lot it's not big at all and hardley noticable i'm just freaking out
