Your exposure history is very low risk for most STIs, because there was no vaginal/anal penetration and no oral sex. A body-to-body massage and hand job do not provide the typical exposure route for
HIV, chlamydia or gonorrhoea. Your ongoing burning after urination and urethral discomfort, however, deserve evaluation rather than repeated empirical antibiotics. Urethral irritation can have infectious as well as non-infectious causes.
Regarding your question about the PCR/NAAT urine test, antibiotics can potentially reduce the amount of detectable bacteria and therefore may affect the ability of some tests to detect an infection. However, you tested 15 days after completing the antibiotics, which is considerably more reassuring than testing immediately during treatment. First-catch/first-void urine is an appropriate specimen for detecting chlamydia and gonorrhoea in men. Therefore, a negative result obtained 15 days after treatment is reassuring, although persistent symptoms warrant clinical reassessment rather than assuming that an STI is still present.
Next Steps
Since you have already received multiple courses of antibiotics and still have intermittent burning/discomfort, I would recommend a direct consultation with us rather than taking further antibiotics empirically. In persistent urethral symptoms, clinicians may consider causes such as Mycoplasma genitalium and Trichomonas vaginalis, while persistent symptoms without objective evidence of urethral inflammation may have non-infectious causes. CDC guidance specifically recommends reassessment and targeted testing rather than simply extending antibiotics.

Health Tips
Stay adequately hydrated and avoid excessive caffeine, alcohol and other bladder/urethral irritants while symptoms are active. Avoid repeatedly taking antibiotics without a confirmed indication, as this can cause side effects and contribute to antimicrobial resistance. Also avoid excessive masturbation or vigorous sexual stimulation temporarily if you notice that it aggravates the burning. If you develop fever, urethral discharge, blood in urine, severe testicular pain/swelling or difficulty passing urine, seek prompt medical evaluation. Thank you
