I have been hear in this forum for about a month.
There have been many individuals with a same scenario.
As far as I have observed, noone got HIV in this kind of an oral exposure. So, risk is very very very low for HIV.
But, I dont know about the risks for other stds. An expert will write to you soon. Do not worry. Everything is going to be allright. Good Luck.
There is absolutely no risk for HIV here.
It's possible, but not likely, that you could have gotten syphilis and gonorrhea from this. Syphilis is uncommon, so I wouldn't worry too much about that, and oral gonorrhea isn't as common as urethral gonorrhea.
At about 5 days post encounter, you can get a throat culture for gonorrhea. I'd be surprised if it was positive.
You can test for syphilis at 6 weeks, but I'd expect that to be negative too.
For me, I'd consider this a "'low enough that there is no conceivable risk and continue' type scenario", but it's up to you if you want to test.
