It has been a while since I spent much time reading about the details of PrEP, so I figured now would be as good a time as any to re-visit the current state of the research.
As it stands today, it seems that there are no life-threatending side-effects from PrEP. BUT, no one has yet used it for decades on-end, so it is impossible to know whether or not long-term use is safe. We don't have time machines, so the only way to know is to wait.
THe effectiveness of PrEP also seems to be going up - the US CDC is saying the research is showing an "over 90%" reduction on infection rates between people using the drug properly, and people not using it. A 90% reduction is obviously good - but it's nowhere near good enough to throw away your condoms and rely on PrEP INSTEAD of condoms!
Don't take my word for that BTW - that's what the US CDC say:

So - taking PrEP sounds like a sensible thing for those who's line of work puts them at risk to take, but using PrEP instead of condoms in the hookup scene is still wildly dangerous and stupid behaviour!
Also - presuring models to use PrEP instead of condoms in porn is still morally reprehensible IMO.
