In this particular encounter, I wore a condom during brief oral sex and, while some of her saliva dripped past the condom onto my shaft, I’m not really worried about that at all. 

Most of the encounter was an uncovered handjob, which I know is not an issue at all,  but at one point, the CSW put the tip of my penis in her mouth for about 2 seconds before I reminded her not to and she stopped. It was not really even in her mouth mostly, just slightly past her lips, but her tongue  definitely licked the opening of my penis. 

I really had not thought much of it, but a week later, I’m having a slight pain/burning sensation when I urinate. I think it’s more likely that I have a UTI (if anything), but I figured I’d be safe and ask about it.

I already have an appointment set to see my GP, in case it’s a UTI.

Was this encounter a risk for any STI? I think not, but I await your response. Thx! 

The encounter you describe was a no risk event, or at least very, very close to that. As you’ve already said, there is no risk from receipt of masturbation. Similarly even if a drop of your partner’s saliva or genital secretions comes into contact with the skin of your penis, there is no risk whatsoever for infection. 

As for the very, very brief episode of oral sex (if you can even call it that), I see no reason for concern as well.  While there are few data on this, on those occasions when STI‘s are transmitted through receipt of oral sex, transmission typically occurs with deeper penetration of the penis into the mouth. Furthermore, the very brief duration of your exposure also makes infection somewhat less likely. After all, remember that most commercial sex workers do not have STIs of any sort and when they do, the throat is least commonly infected.

As for your symptoms, I find myself wondering whether or not following this encounter perhaps you are on the lookout more closely than normal for symptoms. We see this frequently, and find that many of our clients tend to notice otherwise normal sensations when they’re search for genital secretions is  heightened by concerns about a recent encounter.

I hope these thoughts and perspective is helpful. When you see your primary care provider, if your concerns or symptoms persist, please encourage him or her to perform a urine test specifically for gonorrhea or chlamydia which are the two infections most commonly acquired through receipt of oral sex ( a Urinalysis, testing for a UTI would not necessarily detect an STI).   If you test, I am confident your test will be negative. 

If there are continuing concerns or any part of my response is unclear, please use your update to follow ups for clarification. EWH

Just to clarify…. the incident happened exactly 7 days before I had the symptoms I’m mentioning.  Is that enough time for gonorrhea or chlamydia to manifest?
