I closed mouth kissed one guy for a second or two.  

I open mouth (French) kissed another guy for a minute or two.  He proceeded to give me oral sex without a condom.  I ejaculated in his mouth. That was the end of my encounter. 

I’m very concerned with HIV. 

These events were 16 days ago.  

I am taking a PCR RNA test and a 4th gen test at 16 days here in the USA. 

1. Can you please advise on my risk for HIV ? 

2. If my tests are negative (RNA at 16 days/4th gen at 16 days), can I put this behind me ? 

 Please advise and thank you for your service.  

You were not at significant risk for HIV, which is rarely if ever transmitted by kissing, or by fellatio (oral to penile contact). In the 4+ decades of the known world wide HIV/AIDS epidemic, with millions of infected persons, there have been few if any documented to result from kissing, oral to penile sex, or other saliva contact. That you ejaculated in a partner's mouth might have increased his risk of infection if you had HIV or other STI, but had no bearing on your risk. Gonorrhea from kissing is controversial, but is rare -- and probably requires far more prolonged, intensive open mouth kissing than you seem to have had.

For those reasons, from a medical or risk perspective, you really didn't need HIV testing at all. Or any other STIs either. That said, reassurance along is a valid reason for testing -- since you're already started down that path, it makes sense to continue testing until you've had conclusive results. I am confident your HIV test results will be negative, and that will be conclusive:  the RNA test detects 100% of infections 11 days or more after exposure. If you would like additional reassurance, you also could have urine and throat swab tests for gonorrhea, which can be done any time (they're valid 2-3 days after exposure). Finally, you could consider a syphilis blood test after 6 weeks.

In the meantime, you should not be seriously worried. The chance you have any significant infection from these events is near zero.

I hope these comments are helpful. Let me know if anything isn't clear.

2 quick follow ups. Please. 

In fact, these are repeat questions:  1. "the RNA test detects 100% of infections 11 days or more after exposure". 2. " from a medical or risk perspective, you really didn't need HIV testing at all." I haven't changed my mind in the last few hours!

My last questions. 

1. Does “Not a significant risk” mean virtually no risk or not worth testing for ?   

2. Do you think there have been a few cases from kissing/oral to penile/other saliva methods ? 

3. I think my worry is Wayyyyy too high for this encounter.  Do you ? 

Thank you for your time 

2. There might have been such cases, but none have been reported or scientifically documented.

3. I agree.

Anyway, it is pointless to speculate on the risk when you'll very soon know for sure whether or not you were infected. Your test will be negative.
