I had a short unprotected oral situation about 8 months ago. A csw put my penis in her mouth for about 10/15 seconds and I was upset and made it stop. I am pretty much a hypochondriac.  I have always peed often. Well, now 8 months later I got the full std panel and everything came back clean, however, I was unaware of the 2 hour urination window. I had actually urinated 15-20 minutes (and prob five times total before the test) prior to the test. Is my negative test still valid? If so, what could cause me to constantly urinate ( I do drink a ton of water and caffeine) or have the urge to urinate and sometimes it's uncomfortable to pee? I've never had discharge, to my knowledge.  Can I be confident in my test? Thank you very much for your help. 

Welcome to the forum. Thanks for your question.---

Thank you for your response and reassurance.  It may be guilt or shame or something of the sort that has it in my head.  Scared of punishment from the big guy I suppose.  But my last couple of questions are, while I 100% trust your expertise, I'm curious as to why people use the scare tactic of if you pee so close to a test then the bacteria will be flushed out and you could have a false negative... Is there science behind that? Also, I pee a lot but I drink a lot of water.  But I tend to have the urge to pee.  Feels like pee is actually stuck in my urethra, then I do use the restroom and it feels uncomfortable sometimes (I wouldn't ever say painful--I just feel something sometimes) and sometimes I dribble after I am done.  Is this any symptom of an sti?  I will say that since your response, I do physically feel better and symptoms have decreased. Thanks again for your help and providing expertise to this forum.  It's a great thing that you do and I appreciate it.

Urine doesn't flush out infecting bacteria very efficiently. The organisms tightly adhere to infected cells, and DNA testing by PCR and related technologies is little affected by time since voiding. However, when manufacturers developed the current tests, they were sill worried about it (conservatively but unnecessarily) and limited studies to people who hadn't voided for 2 hours, and so FDA regs require that to be stated as a test limitation. It doesn't mean the tests aren't accurate earlier, only that it hasn't been stuided. STD clinics and others with lots of testing experience have long known that it seems to make no difference in test performance, and most STD clinics ignore the time limitation.---

Thanks, Dr. H.  I guess my last question is, with the symptoms described, does it make sense to have a UTI test or is it somewhat normal?  Thanks again (and it really is my last question). 

This sounds to me like someone with a somewhat more reactive lower urinary tract than average, and/or greater perception of normal variations in detrusor (bladder muscle) tone -- i.e. overactive bladder. But if you remain concerned and want further reassurance, mention it to your doctor and/or have a routine urinalysis one of these days.---
