Not OP, and generally don't agree with their point, but this passes the general sanity test.
Considering PREP is targeted almost exclusively to gay men, and HIV is mostly a concern among the sexually active gay male population, saying "young, gay, men" is pretty fitting.
Obviously the value-judgement about how much sex is too much or too risky can't have data to back this up. To me, as long as there is a net reduction in risky behavior that might impact society (not spreading a disease faster than eradicating it), its probably good, but this doesn't seem to be OP's view.
I do not want to discuss a higher incidence of HIV in the group of gay males compared to the whole population. That is a fact that is attributable to the fact that unprotected anal sex comes with a higher infection risk then unprotected vaginal sex.
But the OP claimes that "specifically [young] gay males think as long as they are safe from HIV, they are safe enough." That may be the result of unfortunate wording.
But if not it is an allegation that the OP will have a very hard time to prove.
