Before sex education was common in schools, the rumor was that teens needed someone to tell them about sex. Supposedly, parents weren’t doing it. The media cetainly portrayed it that way. The deception that was sold and believed by too many people was, “They’re going to do it anyway, so teach them what they need to know.”
Sound reasonable? To a point. The point being that in the 1960s, the Catholics I knew were told not to have sex until marriage. That was the only appropriate circumstance to have sex with another person. Chastity was valued and encouraged. Actual, non-sexual dating occurred. Chaperones and strictly enforced rules about when to come back home were also there to help teens.
This was distorted by The Pill. The birth control pill. Which, by the end of the 1960s, was the only excuse you needed to have sex with a guy. Now, 1 in 4 teen girls have an STD. Millions of babies have been aborted.
