Oral Sex, I can't stop thinking about HIV

[Navigator12]

3 months ago I had an encounter where I performed unprotected oral sex on a man with unknown serological status; I had various symptoms, I did not know for sure if I had a submandibular inflammation of the ganglia, I assumed it because of the discomfort; I had a severe sore throat (Tonsillitis) with plaque and diarrhea. Also in the 3rd week I had GERD problems. The point is that I did an antibody test at 30 days (1 week after the possible symptoms of SRA), being negative which reassured me.I must say that I have HSV-2 and the outbreaks have increased in frequency but not in severity

Today after 3 months I can say that I still have neck discomfort, I have had folliculitis on my back and thighs in recent months and I had a mouth infection similar to a yeast infection at 2 months as well. The questions I have are:

1. Are the symptoms described from ARS? (I had a low fever for a long time, but not a high one).

2.How telling is an antibody test at 4 weeks?

3. Could these new symptoms be related to a weakening of the immune system due to HIV?

4. Should I take more tests? which?

The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.

You didn't have a risk for HIV; therefore, you do not have ARS, and any test you take at any time will be negative.
