I've been dealing with what's probably jock itch and I've been sexually active while this was happening and even masturbated. Now there's this swelling on my penis, like half an inch down from the head, forming a ring about the same width around it. I'm circumcised, but there's also a lot of swelling at the bottom of the head, particularly on the foreskin underneath. I'm really worried about all this and I am wondering what the problem could be and how to handle it as soon as possible.
