Talk to Urologist on Difficulty Urinating After Bleeding

About two months ago I did some urethral play (less than 25mm / 1" deep) which resulted in some bleeding (probably less than 12mm / 0.5" deep). I'm not sure how long it lasted, maybe 3 days at most.

A few days after this had happened I noticed that it became harder to pee. I can feel and see my urethra getting stiff when peeing, suggesting that the striction is located where the bleeding was (about 12mm / 0.5" deep). I've tried to insert some sounds (smallest being 6mm / 0.25"), but without success, they just won't go in.

How can this be solved? I've seen some people online saying it can be stretched back to normal just fine, using some small tapered sounds.
