Hi there, I'll try to keep it short and sweet. 34 year old married heterosexual male who made a single mistake. Was drinking at a strip club and ended up going back to a hotel with one of the strippers. She told me she was clean but am not sure of her STI status. She showered prior to the events below too. She gave me unprotected fellatio for about 3-5 minutes in total and I went down on her unprotected for about a minute with finger inserted. We then had vaginal intercourse WITH a condom and attempted anal intercourse for a couple minutes WITH a new condom on. I never ejaculated and the condoms seemed to be properly worn the entire time.

Welcome to our Forum and thanks for your questions.  I'll be pleased to comment.   You do not mention how long ago your misstep was and so, as I answer your question, I will also point out that the longer it has been since your exposure, the more a lack of symptoms shifts the likelihood that you acquired any STI.  If the exposure was more than 10-14 days ago, this risk of infection becomes lower still than the generalities I am about to provide. 

In general, the risk of getting any STI from any single sexual exposure is quite low, particularly when you consider that even most commercial sex workers do not have STIs including HIV and even when they do, the majority of single exposures to infected partners do not lead to infection.  Further, from a biological perspective some sorts of sex acts transmit infection more "efficiently" than others.  Oral sex is not an "efficient" way to transmit STIs.  With these general comments, lets go to your specific questions..

Straight to my responses:

1.  The infections that are of concern would be urethritis (penile infection) or possibly herpes.  For all of these symptoms could have already occurred and most probably would be apparent by day 10.

2. In my opinion your risk is low and I do not feel strongly that testing is needed.  On the other hand, many of our clients like to have the assurance that a negative test provides.  If you choose to test, as I said above, I would do a urine test and a throat swab for gonorrhea. Particularly given your self acknowledged anxiety.  I do NOT recommend testing for herpes in this situation.

3.  I told you there were no proven cases of HIV acquired through either receipt of oral sex or performing oral sex on an infected woman.  The CDC which tends to be conservative lists the risk as less than 1 in 10,000.  I think that number is too high.

4.  Same for condoms if used throughout the sex act and it does not break.

5.  Estimates are that there are about 250 women in the U.S. living with HIV, out of about 150,000,000 females in the country.  It is unlikely your partner had HIV.

6.  See above.  Odds are very, very low.

I would suggest you stay off the internet.  Much of the information there is either wrong or taken out of context.  EWH

Hi there again Dr., thanks again for the prompt reply your answers are definitely providing ease. I know this is the last question and wanted to make sure I understood. I don't mean to question your expertise but you say in answer 5 above there are only 250 women living with HIV in the US, from data seen from the CDC it appears there are roughly 215,000 women living with HIV at the end of 2013. Any clarification on this would be greatly appreciated.

Was hoping to add one more question before you had a chance to review. Statistically speaking would this be a correct assumption:

Sorry for the typo.  The figure I meant to provide was about 250,000 women with HIV in the US, not too different from the 215,000 figure that you found.  Tho only other comment I would make is that properly used condons reduce the risk for HIV acquisition by more than 99%.  Your risk for HIV is tiny and, as I said, not something to worry about.---

Can't thank you enough!!
