Hi, it's been 3 months since I had oral sex. I gave a completly uknown person a brief BJ without ejaculation (the whole act lasted about 10 seconds). I haven't had any symptoms (exepct for the fact that for the past few days I have a frequent urge to urinate), but I am extremely anxious. He also fingered rimmed me, but, as far as I know, these activities don't pose any risk for me. What STI should I test for?
