Even as early as the 50’s and 60’s there was “Sex Ed” in schools

Court House - Even as early as the 50’s and 60’s there was “Sex Ed” in schools, even the Parochial (Catholic) schools. I remember that all the 6th or 7th grade girls (girls only) were herded into the auditorium to watch a short film and presentation on what to expect in the next year or two.. If that’s not “Sex Ed”, I don’t know what is. Should that be banned too?
