Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
What i could make out from your history is that you had sex for the first time around a week back with your girl friend who was also a virgin. Post sex, you developed a tiny cut near the urinary opening. You also had slight pain, after you withdrew your penis. This is common while having sex for the first time, since the vagina will be tight and also due to lack of lubrication. The cut may have arisen due to the same reason, and that also makes you prone for UTI.
Since then you have been peeing a lot. This can again indicate UTI. I will advise a course of prophylactic antibiotics for you, since there is also a cut, chances of infection are high. Along with this please keep drinking 3-4 liters of water everyday. Less water intake will also let the bacteria grow in the urinary tract.
I suggest a course of :
1) Tab. Norfloxacin 400 mg 2 times daily, 1-0-1 for 5 days.
2) If the cut does not start healing by itself, you can apply Mupirocin ointment but wait for 3 days. Since it is near the urinary opening, i won't ask you to start applying the ointment right away, since it might burn a bit. However it is expected to heal in 3-4 days time. Only if there are no signs of healing, you can start applying the ointment too.
Feel free to discuss further,
Regards.
