The problem with that messaging is it’s hard to take back. Even in 2022, I have straight friends who regularly have unprotected sex with random women and don’t think HIV applies to them because they’re not gay.
I'm a gay man, and I'm on PrEP because I know I'm at higher risk of HIV. If I were straight and (1) neither I nor my partners used IV drugs, (2) neither I nor my partners had any visible STDs and I got checked for STDs regularly and (3) I were circumcized, to be honest I'd be fine having unprotected sex with random women because my chance of acquiring HIV would be exceedingly, exceedingly low. My chance of acquiring other STDs, especially Chlamydia, would be much higher, but if I were getting checked regularly it seems like a reasonable risk for a treatable disease.
I am on prep too but still there’s a difference between consciously accepting a certain level of risk vs just assuming the risk is nonexistent because of poorly communicated information
