Dr. Hanif warmly Welcomes you!
Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns.
It doesn't look like a concerning medical issue until unless you have
fever, and other related signs and symptoms. What happens is, the liquid over the urethral opening looks like making bubbles at the end of the urination.
If you start feeling itching in the urethral opening area, burning micturation, fever or other gastrointestinal symptoms then get your check up done by physician.
Possibility in such completed cases is the fistula formation between bladder and intestine and air leaks from intestine to urethra and out. But thats a surgical emergency and i dont think you have it.
Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to 'ask me a question' directly from my profile.
Have a wonderful time ahead.
Best Regards!
DR. MUHAMMAD M. HANIF
