If I swirled my tongue around the tip of a penis and gave a little suck to the tip- do I need to have any concerns or need to test ? Spec bacterial infections?  ( this was a work friend) ( regret actions - )

Welcome to our Forum.  Thanks for your question.  I'll be glad to comment.

Among penetrative sexual contacts, oral sex is the lowest risk for acquistion of STIs and there is minimal risk for most.  The risk for acquistion of HIV in the (I presume) relatively unlikely situation that your co-worker has untreated HIV is estimated to be less than 1 infection for every 10,000 exposures (i.e. like performing oral sex on a person with HIV daily for more than 27 years).  The risk for chlamydia and syphilis is similarly very low.  The main STI acquired through oral sex is gonorrhea and that too is uncommon.

In your specific case, I presume that your partner is rather low risk to start with and the brevity of sex act makes your risk even lower than average.  Personally, were I in your situation, I would not bother to test but, testing is always a personal decision and if you choose to get tested for gonorrhea (the test typically tests for both gonorrhea and chlamydia at the same time), I anticipate that the test will show that you were not infected.  Should you chose to test, the main test you need is a throat swab for gonorrhea.

I hope this information is helpful.  If any part of this reply is unclear, you have up to 2 additional follow-ups for clarigfication.  EWH

Thanks for the service you provide and for taking the time to answer my question. I am fairly certain I am safe, especially from a gonorrhea stand point, as I have read that most men exhibit uretheral symptoms if infected with gonorrhea. I have also read on this site that in order for chlamydia or gonorrhea to be transmitted to the throat, direct contact with the penis in the throat must happen, is the contact/transmission due to the mucus coming in contact with the mucous membrane of the throat or does the bacteria live on the skin? I am sorry, but I am very sti naive - if there was no contact with the throat would the risk be virtually zero? This interaction might have lasted 1 second. 

I have heard that azithromycin is prescribed for chlamydia- if I took 500mg an hour after the encounter, could that prevent an infection if exposed from establishing?

The bacteria does not live on the skin.  This was a close to no risk exposure but not 100%. The fact that you took azithromycin after the encounter reduces your risk even more and would likely prevent infection.

As I said above, if you are concerned, test.  That said, I anticipate that if you test, you were not infected by the activities you describe.  Sorry I cannot be absolute.  EWH

I understand you can not be absolute. With that said, I am hesitant to test because I read chlamydia throat tests are not approved, and I took the azithromycin- which could mess up the test…correct? 

Before we part ways, again I am naive when it comes to sexual experiences- I understand that 1g is the recommended dose - I only took 500mg - does that change your view point on prevention? I just wanted to be clear with the dose I took, in case you over looked that aspect- since you take time out of your day to answer these questions, and I am sure you answer a lot daily. Again I appreciate your passion. .

Final answers. Chlamydia very, very rarely infects the throat, and in your case, given the very low risk nature of your exposure, I would not be concerned. 

You are correct that you took a lower than recommended dose of azithromycin. Nonetheless, if you choose to test, the results of testing will be accurate.

This completes this thread. EWH
