Negative guy here, and as I haven't had sex with ANYONE in at least 8 months and I've been tested recently, I know it for sure. That said โฆ I hate the ignorance and fear that's persisting in our community about this issue.
We need to absorb this fact, or else we're being just as preposterous as U.S. senators entering the congressional floor with snowballs and trying to claim that climate change isn't real, and they've proven practically every scientist on Earth wrong with that one snowball -- you need to listen to the people with the ph.d's, and not your gut fears that have been drilled into your head. The fact is, all the actual scientific evidence shows that you're probably a lot safer with someone who's positive and knows their status than you are with someone who thinks that they're negative (and tells you so).
would not knowingly have oral or anal sex with someone who told me they were HIV positive even if they had a low viral load or even if I was on PrEP or Truvada unless for some reason I was so in love with them that I decided to take the risk
The thing is, if you're with someone who knows they're HIV positive and have an undetectable viral load, whether you're on PrEP or not (and it's a good idea to be on it), your risk is actually lower than having sex with someone who tells you that they're negative but their last test was โฆ hell, even two weeks ago. Remember that the virus isn't strongly detectable until you've been infected for half a year as it is.
All the science supports that fact -- you literally, LITERALLY, have less of a chance of becoming infected by someone that's positive yet provably undetectable (when it's demonstrably and test-verified undetectable, as far as we know so far, the risk is essentially zero) than you are with someone that just comes up to you and says, "Yeah, I'm negative, here's my test from last month."
What "risk" is it you're not willing to take? It seems like the imaginary one in your head where you still want to believe your programmed fear and not scientists and doctors.
