In your two threads almost 3 years ago, we discussed types of exposure that do and do not transmit HIV. The bottom line is that without penetrative sex or shared drug injection equipment, you will never get HIV. Even perfoming oral sex on an infected male, with ejaculation in the mouth, is almost risk free, with an esimtated risk of 1 in 10,000 if the penile partner has HIV. That's equivalent to giving BJs to infected men, with ejaculation and swallowing semen, once daily for 27 years before transmission might be likely. Knowing that, you will understand that the tiny amount of semen to which you might have been exposed in the situation described carries little or no risk. This level of exposure also is risk free for all practical purposes for other STDs. Finally, I'll point out you don't even know such an exposure occurred:  just sitting near someone receiving oral sex is absolutely no risk. I cannot imagine how that could result in semen flying through the air to reach your mouth or face.

So all is well. For sure you do not need testing and should continue your normal sexual practices with your regular partner.

Let me know if anything isn't clear. Best wishes and stay safe.

Definitely no risk. Do your best to move on and let it go.

That concludes this thread.
