Had an exposure 1 week ago where reciprocal oral was done between me (M) and another male. Neither of us finished in the others, and he didn’t finish at all. The whole encounter was less than 15 minutes. I don’t have any of the systems of chlamydia or Gonor, but noticed a small bump on the side of penis. It doesn’t look like other google images of STDs (syphilis or HSV), but I don’t know. Based on the encounter

Welcome to the Forum. Thanks for your questions and your implied confidence in our service.  I'll be glad to comment. The exposures you describe was virtually no risk.  To expand on that, regarding HIV, the estimated risk of performing unprotected oral sex on an HIV infected, untreated man is less than, on average, 1 infection in 10,000 exposures (i.e. it would take over 27 years to be exposed 10,000 times if you performed oral sex on a person daily.  Further, there are no known cases of HIV which have been acquired from receiving oral sex from an infected person. With You are not susceptible to HSV-1 because you have antibodies and HSV-2 is almost never transmitted from giving or receiving oral sex.  ---

Can you please clarify why virtually “no risk”? Do you not recommend testing after an oral encounter where no condom was used? I don’t have any burning sensation but feel some itchiness around pee hole. I can’t tell if it’s just in my head, but it doesn’t feel itchy and present. There is no burning sensation when peeing or any discharge.

On the Forum we use "virtually no risk" rather than no risk because in science and medicine you can never say never.  As I already said, "To expand on that, regarding HIV, the estimated risk of performing unprotected oral sex on an HIV infected, untreated man is less than, on average, 1 infection in 10,000 exposures (i.e. it would take over 27 years to be exposed 10,000 times if you performed oral sex on a person daily.  Further, there are no known cases of HIV which have been acquired from receiving oral sex from an infected person."  Those are the scientific data that are available.  Perhaps somewhere somebody got HIV from receipt of oral sex but that remains unproven.  The risk is far far lower than your risk of getting stuck by lightening.  If that's not low enough for you, then you should test as I said.  Personally, I would not be worried.  EWH  ---

Hi 

1.  The CDC tends to be conservatives and lists possible symptoms without regard to their likelihood.  By far, the most common STI acquired through giving or receiving oral sex with a male partner is gonorrhea but these infections are uncommon both because oral infections are uncommon and poorly transmitted. Both the biological efficiency of transmission and acquistion of all STIs, including gonorrhea are lower for oral sex than other types of penetrative sexual encounters (i.e. oral - genital or ano-genital).  Further, most people do not have STIs and when they do, most infections are genital, not oral.---
