Narrow urethra? Isn’t that what Hank Hill is afflicted with?
Anyway, I am no doctor, but it sounds like you made the classic newbie mistake of doing too much too soon. Give it as long as it needs to heal. It may be another 6 months! But don’t even think about starting PE again until you are 100 % sure it is healed.
I hope it isn’t broken forever, but if it is it just goes to show that ignoring the wisdom of TP will just get you injured.
