Your experience that you describe does NOT present a risk for acquiring genital herpes. Period. From everything that you describe, there was not genital to genital contact nor was there her mouth to your genitals contact. Absolutely nothing you’ve said makes me worry about you getting herpes at this encounter. I think whatever symptoms you are having have nothing whatsoever to do with a new case of genital herpes.
It is unfortunate that your doctor prescribed antibiotics without knowing if your had white cells in your urine that would define a urinary tract infection. True UTI’s in men are really quite rare (urethritis due to an STI are quite common) and I’m not sure what to make of your feeling of incomplete urination. However, what I can tell you is that it isn’t new herpes infection!
I am curious – have you had an IgG antibody test in the past so that you know your herpes status already?
