I do not know their HIV status or sexual partner history. However, I know that both are not prostitutes or needle users; and both work in respectable jobs.

Whether or not these events were "a grave mistake" might be true emotionally, but it certainly was not from the standpoints of infection risk or other medical issues. These were zero risk events in regard to any and all STDs. None are transmitted by kissing, by fingering or any other hand-genital contact, or by mouth contact with non-genital areas, including breasts and nipples. You have already answered your own question in realizing that no testing is needed.

I'm not sure what more you expect in regard to a "medical/science standpoint." The absence of such risk is a medical evaluation and strongly science based. It isn't possible to review the biological reasons why there was no risk, at least not in detail. But it comes down to STI bacterial not generally being found in some areas (like saliva or very often in the mouth); the inherent inefficiency of transmission even if infection is present; and that not enough of the causative bacteria and viruses can be carried on fingers to other potentially injectable body sites.

I would advise no testing and that you continue your usually sexual practices with your regular partner.

I hope these comments are helpful. Let me know if anything isn't clear.

So in conclusion: I need to put HIV out of my head for good and move on from this without any worry at all? (aka. get a grip, I’m in the clear)

From an educational perspective, in terms of avoiding HIV my entire life, I understand from your historic replies that all that needs to be done is (1) don’t have unprotected sexual intercourse with an unknown partner; and (2) do not share needles.

Is this still your stance today?

Thank you for your help.

Best wishes and stay safe.
