This should be good.. Completely non-snarky response. Provided you aren't just trolling us and this actually happened you might want to see a doctor as you might have a problem with your bladder or the urinary track muscles.
If you maintain a high dairy diet you should be able to make the color of your piss a foggy white. Then she will never know.
Full bladder has precedence over pleasure ejaculation? I dunno. What's wrong with you? Asking this type of problem with a sports forum. Go to a doctor or sex therapist you freak.
pics? SERIOUS ANSWER: GOSH, you kids never learn... anyway... It is impossible for the human body to ejaculate AND urinate at the same time. Perhaps you have a lot of "pre-c*m", which sterilizes the pathway of the semen and exits the urethra BEFORE the actual semen. This liquid tends to be clear and viscous, and is NOT like urine at all. When your reproductive system is producing semen, it doesn't expel urine. AFTER you've ejaculated you could urinate, but not DURING (when your body is stimulated and 'horny') or just before. Are you sure you actually urinated or you just squirted some pre-c*m out? It is possible to have maybe up to an ounce if your body is not used to ejaculating. I recommend trying this thread or question or situation again. EDIT: I see Yonkers has a better scientific answer. Well done, sir. NO to your question, aussiejack
OP, it is COMPLETELY NORMAL to pee in your GFs mouth. You'll have to excuse all the jokesters here on Clutchfans telling you there is something wrong with your junk. There isn't. Tell your GF this is a common thing and just tell her to get used to guzzling your pee. Source: I'm a doctor.
