Welcome to our Forum and thanks for your implied confidence in your service.  I'll be glad to comment.  The encounter you describe was virtually no risk.  Your partner provided evidence that she was not infected with HIV on January 3 2023 and having not become infected up to that point there is little chance that she was infected in the interval since her prior test.  In addition, your exposures included both giving and receiving fellatio;  There are no proven cases of HIV acquired through receipt of oral sex from an infected person and the average risk of acquiring HIV from performing HIV on an infected partner is less than 1 infection for every 10,000 encounters (i.e. 99.99% of exposures will NOT lead to infection).  Putting all of this information together, there is virtually no risk that you were infected by your encounter on January 16.  ---

Hello Dr Hook, Firstly thank you for your advice. i just have a few further questions.

I apologize for the lack of clarity in my answer.  IF your partner had untreated HIV (unlikely), there is no known risk for infection from receiving UNPROTECTED oral sex and the risk of infection from performing UNPROTECTED oral sex on an untreated, infected partner is estimated to be less than one infection per 10,000 exposures.  Your encounter was virtually no risk from a statistical perspective.  Please don’t worry.  EWH ---
