Safe sex with other men, even with relatively low risk encounters, you ought to be getting
regularRegular insulin tests for HIV and common STDs. Intervals of 1-2 years make sense. On that basis alone, you should be tested soon. It's just common sense. In addition, all MSM are ethically obligated to know their HIV status with great confidence in order to discuss it with their potential partners before having sex, even when safe practices are planned.
OK, lecture over. What are the odds you were infected during the receptive anal encounter 2 years ago? Nearly zero: most men don't lie about HIV status, so your partner almost certainly wasn't infected; and the risk undoubtedly is reduced by lack of intra-rectal ejaculation. That said, nobody can guarantee your partner wasn't in the window period before a positive blood test -- which is when HIV is most readily transmitted, by far.
As far as being the insertive partner in oral sex (which is how I interpret the bleeped word), the risk is so low that some experts believe the risk to be zero; and all experts believe it is exceedingly low, with data from CDC suggesting an average transmission chance of once for every 20,000 exposures. (That's equivalent to receiving a ** once daily by infected men for 55 years and maybe never getting infected.)
Certain STDs, on the other hand, are fairly common after oral sex. However, it is rare for any STD to cause symptoms only 2 days later. Gonorrhea or herpes are possibilities; the others that can be acquired from a partner's mouth (like nongonococcal urethritis [NGU] typically don't have symptoms before 5-7 days and often up to 2 weeks. Some sort of physical irritation seems more likely. That said, it was smart for you to be examined. Most likely your gonorrhea test will be negative. If not, or if your symptoms persist, continue to work with your doctor about alternative causes.
As implied above, I would have advised you to have the HIV test your doctor recommended. In my opinion, there is no valid reason to have HIV testing done "privately", i.e. separate from general medical care. If the result is negative, who cares that it's on your record? Having a negative HIV test stopped being a true cause of discrmination 20 years ago. And if the result were positive, of course you doctor has to know in order to recommend other tests, treatment, etc. It is not possible to get anonymous care for HIV.
Bottom line: It is extremely unlikely you have HIV from either of the sexual encounters described here. (You don't say what if any other exposures there might have been over the past 2 years.) But for the reasons stated above, you should be tested.
I hope this helps. And please do get into the "do ask, do tell" habit. In the long run, open exchange of HIV information, before having sex with a new partner, is just as important a safe sex strategy as condoms for anal sex.
