hi dear if u developed itching and irritation immediately or just within a day after the latest sex it might be due to condom allergy
and not a std
. but if there was a gap of few days between sex and ur symptoms, it might be an infection. any way dont worry much. here are my suggestions...
wash ur glans
with normal saline daily three times for a week.
take tablet azithromycin
1 gram single dose. u ll be fine.
