You are not annoying but it is important to realize the statement about only an 92 percent accuracy rate is confusing and, well, inaccurate.
The problem with home testing is that this does allow folks to run out and purchase these kits waaay too early after a possible exposure. It's not unusual for people to buy and test just days after a potential exposure; long before there are enough antibodies present to be picked up by these tests. The result (if they are infected) would be a "false negative" test result. Later on (when adequate time has passed), follow up testing would show a positive test result.
This is not the case with you or your husband. You indicated that he tested at least four months past his last possible exposure after his affair. If this affair had left him infected, his test result would, undoubtedly have come back as "reactive" (positive). It came back as negative as did his second test. There is no way these two test results were inaccurate. He does not have the virus and thus he cannot infect you with it.
That is the truth and even if he continues to test from now until "the cows the come home" the results will be no different.
I hope this brings you some comfort and allows you to put all these concerns behind you.
There is no need to test further (although many OBGYNs will now include HIV screening tests as part of their routine prenatal workups with pregnant women so don't be surprised if one is ordered when you do become pregnant).
Your husband has tested negative.
You have tested negative.
These tests have been used many, many, many times to confirm folks status. They are quite accurate. You can trust the results.
If you cannot it might be a good idea to consider some counseling before taking the next step regarding starting a family.
Perhaps this slight burning is an indication of a urinary tract infection (sorry; I can't diagnose UTI's over the internet).
This, of course, has nothing to do with HIV. Urinary tract infections are depressingly common.
What you need to keep in focus are the two things that have been pointed out before; your negative test results and the fact that simply getting sexual fluids on ones hand does not transmit the virus to someone.
Look; you did everything right when you had sex and used a condom. Instead of excessively worrying about HIV you should be congratulating yourself on what a smart person you were to do this!
You had PROTECTED intercourse! PROTECTED. That means even if this prostitute was infected (something you are totally unaware of) the virus could not, in any shape, way or form, enter your body THROUGH AN INTACT CONDOM.
