You indeed describe entirely safe exposures -- that is, the particular events you describe do not affect your previous track record that you have always been very safe. Although cuts or wounds on the hand are often thought of as HIV risks if exposed to blood, semen, or other body fluids, it really isn't true. The biological reason probably is that except when wounds are very fresh (typically caused by a sharp instrument contaminated with HIV), even partial healing creates barriers of fibrin (blood clot) and cells that block HIV, at least enough that transmission doesn't occur. There has never been a known case of HIV transmission by fingering, hand genital contact, or exposure of an old wound to blood -- and if you think about it, this is despite what must have been billions of fingering incidents by people with hangnails or other finger wounds. And no known cases, ever.

As for oral sex, that's very low risk even without condoms. Indeed, most experts do not recommend condoms for oral sex; the risk of HIV or other STDs is too low for it to make much sense. Fine to use them for extra safety if acceptable to both partners, but really not a serious risk if not used. So the broken condom event shouldn't concern you much. One statistic for fellatio (penile-oral contact), the HIV risk from the penile to oral partner is one in 10,000. That's equivalent to giving BJs to infected men, with ejactulation in the mouth, once daily for 27 years before HIV transmission might be likely.

All non-monogamous sexually active persons should be tested for HIV from time to time. Even though these particular events are very low to zero risk, if you've never been HIV tested, you probably should do it. This doesn't mean I really beieve these events were risky; I do not. But just asking the question means HIV is on your mind, and you might find a negative test even more reassuring than my evaluation based on probability and statistics.

I hope this has helped. Let me know if anything isn't clear. Best wishes--   HHH, MD

That completes the two follow-up comments and replies included with each question, and so closes out this thread. I hope the discussion has been helpful. Best wishes and stay safe.
