Need help- might get Circumcised

I couldn’t retract at all but was able to retract when flaccid- that was 2 years ago.
I started stretching, but cannot for long as i have swelling of frenulum and its very painful.
(It might be because post masterbation)
I am not sure i am just stuck now.
I have tried to use rings but haven’t helped much.
What to do?
Stop PMO?
