Talk to Urologist on Urologists

Hi I think I have std Symptoms are painful urination on and off and weird sensation like burning on the right inside of the penis. Precociously it goes and comes but now I feel like it is progressing to the testicles maybe. Started after sex. Did a urine culture twice no bacteria found. Did a urinalysis all fine no wbc no pus. Reading online most symptoms point towards my feeling it could be chalamadyia. What is the other name of tests that I can get before going to a doctor for any antibiotic. I’m afraid of taking antibiotic unless necessary as I heard it can strain kidneys. Had Kidney pain few years back. Please guide.
