For the burning pee part, briefly, because this is the HIV forum, you can get gonorrhea, chlamydia and NGU from oral sex. You need to see a doctor to get tested to make sure you get the correct medication.
Don't try to treat yourself. It could also be dehydration. See a doctor. If you have further questions, post in the STDs forum - https://

The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
As you can see, you did not do any of the activities on the list of risks.
If you do not engage in any of the activities I mentioned above with someone HIV+ or whose HIV status is unknown to you, you will NEVER have to worry about getting HIV. There is no information you could add about this event that would make it a risk for HIV.
See your doctor for your non-HIV related medical issues.
