Exposure history:
Did something stupid.. Got a body to body Massage and hand job in May 1st week 2026.
No penetrative vaginal/anal sex and no oral sex.
Current symptoms:
Burning after urination (fluctuates from 1/10 to 5/10) which stays for few minutes to hours
urethral discomfort.
Sometimes feel feverish but no fever when measured
Treatment received without any Testing :
Nitrofurantoin 2* 5 days.
Doxycycline –2* 10 days

I tested negative for sti after stopping the antibiotics for 15days ( held urine for 2 hours.. and then gave the first catch sample).. Will antibiotics have affect on the pcr urine test?

Body-to-body massage + hand job only → very low STI risk.
No vaginal/anal/oral sex → HIV risk is essentially negligible.
Burning/urethral discomfort may be due to irritation, UTI, or urethritis.
If persistent, do first-void urine NAAT for gonorrhoea/chlamydia ± urine routine/culture.
Antibiotics can reduce PCR/NAAT sensitivity, so ideally test before antibiotics.
