The 1950s through 1970s were the golden ages of antibiotics. New ones discovered all the time, and minimal resistance. Stuff like syphilis was readily curable.
So Hep B, herpes, HPV and anything else that is viral and not readily cured by a course of antibiotics is simply not a concern?
I’m not a doctor, gay man, or a sexually active person, but it doesn’t take much research to figure out that unprotected sex with random people will cause health problems that cannot be waved off with a simple pill.
Believe it or not, sexually transmitted diseases were not much of a concern from the sexual revolution of the 1960s until the arrival of herpes, or at least the re-branding of herpes as a very bad thing. [1]
So everyone was afraid of the herps, an untreatable condition.

For the most part, correct. Herpes and HPV hit basically everyone; chances are you've had one or both. Hep B is less prevalent, but still quite widespread (Wiki says 1/3 of people will get it eventually), and in most cases has minimal symptoms.
