Thanks for your query.Based on the facts that you have posted it appears that you may have a flimsy stricture of the Terminal Urethra
However this can be confirmed only on following tests
1) Cystoscopic examination of urethra passage by a qualified Urologist
2) Retrograde Cysto-Urethrogram.
If confirmed you may need to undergo an endoscopic surgery
of Optical Internal Urethrotomy
Please discuss the possibility with your urologist.
