I am 25 and I think I might've used too much force when I was masturbating last week. Immediately after I ejaculated at first I felt a burning sensation around my entire penis but that quickly subsided after I went to the bathroom and urinated. Afterwards I felt a burning/tingling/irritation around in my urethra/penis tip that has not gone away since. I feel it constantly and the only time I feel any type of relief is when I urinate or masturbate, with no burning sensation on either one. Im not circumcised but when I peel back the skin to check for any signs of infection I don't see any signs of inflammation or anything abnormal that sticks out. My question is is there anything I can do to treat these symptoms like applying heat or ice to the penile region or should I just stop masturbating, which probably is not helping matters, leave it alone and hopefully it heals on its own. Or is the only way I can treat this going to the doctor and get prescribed antibiotics. Any advice would be helpful thanks
