Hello,
Thank you for your post.
Because the condom came off during the anal penetration, there would have been a potential risk of HIV infection. However I would possibly estimate this to be relatively low: there was no ejaculation, and a condom was used for most of the penetration. In any case, the estimated risk of receptive unprotected anal intercourse with a HIV positive individual is around 3% per sexual encounter. In your case, this would be less due to the factors mentioned above. Therefore it was probably the right decision not to have taken PEP.
Your symptoms are not all consistent with acute HIV sero-conversion, as they are not specific and one cannot rely on these. A lot of it, it is most likely to be related to your worries and anxieties.
You could have a PCR RNA test now, which has a very high level of reliability after 10 days. Subsequently a HIV Duo or Combo after 4 weeks will be totally conclusive. I would also advise you to get tested for all other STDs.
Best wishes,
Dr José
