[Question #3389] Single Encounter

37 months ago
Here is my scenario... on Jan 30 2018, I was tested for HIV, gonorrhea, and clamydia. All were negative. On Feb 27 2018, I received unprotected oral sex from an exotic dancer (stripper). I am a male and the dancer is a female. This has been my only encounter since my tests in Jan. I did ejaculate in her mouth.

These are my questions:
1. What are the chances of contracting HIV from this encounter?
2. What are the chances of contracting other STDS from this encounter? 
3. If I am at risk, how long do I have to wait before getting tested?
4. If I need testing, then which ones should I ask for?
5. The dancer did not appear to have the healthiest teeth. Not sure about the gums. Is there any added risk due to her oral health?
6. Thank you so much for considering my questions. I am done with this adulterous lifestyle.

Welcome to ur Forum. I will be glad to address your questions.  The encounter you describe was low risk.  Most commercial sex workers/exotic dancers do not  have HIV or other STIs and even when they do, most exposures to infected sex partners do not lead to infection.  Oral sex is likely a less efficient (from a biological perspective) mechanism of transmission of infection than genital or rectal contact.  As for your specific questions:

1. What are the chances of contracting HIV from this encounter?
Your risk is essentially zero.  There are no cases of HIV which have been proven to have been acquired due to receipt of oral sex.

2. What are the chances of contracting other STDS from this encounter? 
There is a small risk.  The most common problems are either gonorrhea of non-gonococcal urethritis NGU) caused by mouth organisms introduced in to the urethra during sex.  Chlamydia is very, very rare.  Most of these infections are symptomatic and would cause symptoms within 4-7 days of contact but testing for the STIs mentioned is reasonable if you have concerns. 

3. If I am at risk, how long do I have to wait before getting tested?
See above.  Testing for these infections would be effective any time more than 2-3 days after exposure. 

4. If I need testing, then which ones should I ask for?
Have a urine test for gonorrhea and chlamydia.  The urine can also be tested for white blood cells which would indicate non-chlamydial NGU from mouth organisms.  The urine should be collected just as you begin to urine, not from mid-stream once you have begun to urinate.  Testing for syphilis which is very unlikely, would not be completely accurate until more than 6 weeks after exposure although acquisition of syphilis from receipt of oral sex is very rare.  we do not recommend blood tests for herpes.   

5. The dancer did not appear to have the healthiest teeth. Not sure about the gums. Is there any added risk due to her oral health?
No, this should not change your risk for infection.

I hope these responses are helpful.  EWH
