Hold on... most?
I think it was quite the opposite. When it became clear in the 80's that a condom was the best way to avoid getting HIV most people started practicing safe sex all the way till PrEP was created. I was one of them, all the escorts I've hired also did the same and would hang up the phone at the simplest insinuation of going BB.
BB sex before PrEP was an act of irresponsible madness and only common among PNP folks and other "marginal" segments of the gay community!
Fratboys would rape drunk girls while wearing a condom... yes, they were criminal perverts but not crazy to put their lives at risk.
