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.
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.
