PSE has never meant BBFS, no matter what urban dictionary says. It is very concerning that more and more guys are seeking this service, and more and more girls are advertising. Same goes for PS (bare) that is increasingly sought after in the MP world. As a guy who was a young man when the HIV epidemic was raging, just before highly effective treatment became widely available it still shocks me that people seek these services when they engage in this hobby. Used to be BBFS could equal DWS (death wish service), but our collective memory of that time fades I guess, and “creampie” porn has fetishized it as well. We need to remember tho that while HIV is treatable, it’s still forever, and you are at risk unless you are on PREP. Still, number of other STIs are possible, rates of gonorrhea, syphillis and chlamydia are skyrocketing, and increasingly there are cases of highly drug resistant forms of these diseases.
