Hi,
Noted the history about having yeast infection in your partner, had unprotected sex followed by development of 5 little
white spots on the rim of penis.
This is surely an yeast infection, a condition called
balanoposthitis.
I would advise you the following:
Clean the penis 2-4 times a day with plain water, no need of soaps or so.
Apply liquid
povidone iodine locally 2-4 times a day.
Use loose clothes.
Avoid hot and humid atmosphere.
Let the area be well ventilated.
This may clar off within a few days to a week.
If it does not then you may need additional prescription based medications and
Metronidazole ointment to be applied locally.
Use condom every time.
Get blood sugar checked to be sure about not having diabetes.
If the problem is recurrent then you may need
circumcision too.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
