Hi AnxiousNoMore, tks for your response.
I have mouth meth in some cavities, does this have no effect?
This answers all your questions and if you think of any others, then you can get the answer if you just reread about the 3.
You had no risk for HIV so your pep was a waste of time. Even if you had a risk, it is not smart to take a medication for less days than recommended or take one when you need 2 - thankfully that is irrelevant since you had no risk, but keep it in mind next time. I wouldn't tell the wife because she will be hurt and there is no HIV disease for you or her to worry about. You can check the std forum for info on that though.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.
Only 3 adult risks are the following:
1. unprotected penetrating vaginal with a penis
2. unprotected penetrating anal sex with a penis
3. sharing needles that you inject with. Knowing these 3 are all you need to know to protect yourself against HIV. The situation you describe is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. Doctors have calculated the risk from what you describe to be less than that of being hit by a meteor, therefore no one will get HIV from what you did in the next 40 years of your life either. The above HIV science is 40 years old and very well established, so no detail that you can add to your encounter will change it from zero risk.
