Oral sex is safe sex in regard to HIV:  there has never been a scientifically proved case of HIV being transmitted oral to penis. Based on HIV infected persons' beliefs about how they caught their infections, CDC calculates a risk of 1 in 20,000, if the oral partner has HIV. That's equivalent to receiving BJs by infected partners once daily for 55 years before HIV transmission might be considered likely. And that's only with known infected partners. The chance any particular sexually active female has HIV is under one in a thousand -- so your risk of HIV is zero for all practical purposes. As for your symptoms, they are not typical of a acute retroviral syndrome (ARS, i.e. a new HIV infection). No other STD is likely either; I am more suspicious of a non-HIV viral infection. 

To your specific questions:  1) Probably you were not exposed to HIV; and even if your oral sex partner has HIV, the chance you were infected is near zero. 2) These symptoms are not typical of ARS (early HIV infection), but I cannot say with 100% certainty). 3,4) Therefore, it makes sense for you to be tested for HIV and to hold of on sex with your wife until you have the result. I suggest testing primarily for reassurance -- you can definitely expect a negative result, which will be very reassuring (probably a lot more reassuring than anything I can say). And to be maximally safe (and maximally reassured), have a blood test for syphilis as well. Rather than arranging testing on your own (like a laboratory you identify online), I would suggest you see your personal physician to evaluate the overall situation -- to diagnose your ongoing symptoms as well as for HIV and syphilis testing.

I'll be happy to comment further if you'd like to let me know the results of your tests and/or your doctor's opinion and advice. In the meantime, I hope this information is helpful. Let me know if anything isn't clear.

An initial oral herpes certainly could cause painful sores in the mouth, as well as inflamed lymph nodes of the neck or under the jaw. (Recurrent herpes outbreaks almost always are outside the lips.) However, initial oral herpes symptoms usually start within a few days of exposure, not two weeks later; so if it's herpes, you didn't catch it during the sexual exposure described. Other viral infections also can be responsible. As for syphilis, the timing is right for your oral sores, but you can't get syphilis orally unless your mouth is exposed, either by performing oral sex on your partner (which you don't mention) or by kissing her (also not mentioned). The same is true of herpes.

If you follow through with testing and/or a doctor visit, I'll be happy to comment further if you'd like to let me know the outcomes. Until then, however, I really can't say more and won't have further advice. 

Hello, a test result appeared:(hiv combo 4th) negative

syphilis test remains after two weeks. 

Ask about the combo test:

Does the person have corona or because he took the corona vaccine affects the result?  Does anxiety and stress delay the emergence of antibodies?  

Is the examination conclusive after 45 days?

Your syphilis test was done "after two weeks" since when? The risk of syphilis from the exposure described is very low. However, two weeks is too early for conclusive syphilis testing; a test needs to be done 6 weeks or more after exposure, or at least 4 weeks after onset of symptoms (such as oral sores).

I have one last question and I apologize for the inconvenience. But as I told you before, I took a test (combo ag+ab 4th) 45 days after exposure

That's one exchange beyond the standard of two follow-up comments and replies, and so ends this thread. I hope the discussion has been helpful. Good luck in regard to COVID!
