Hello
Thanks for query .

There is no precise time frame mentioned any where in books or practical about time interval between ejaculation and passing urine .

UTI can occur after oral sex if the oral cavity is full of bacterial flora .

If you have urinary symptoms or even otherwise it is safe to take antibiotics like Norfloxacin or Nitrofurantoin twice daily as a prophylaxis to prevent getting UTI.
