So I was in school in 80's and everyone I know has this knowledge.
So at what age was it no longer taught in school?
Or is it that people just forgot.
From what I remember, the 'Let children be Children' protests from people wanting to keep their daughters (mostly) ignorant of their bodies revved up in the 1990s. It's when I recall seeing sad face parents in news articles complaining that telling children the names of their body parts was exactly the same as telling five year olds to have gay sex. Purely anecdotally (as is all of this), it seemed to coincide with an increase in Evangelical Christianity, particularly in the wish to provide PSHEE education in schools.
I was particularly enraged by my eldest's sex ed in year 7/8, though. yes, it was provided by a Youth Worker. A Youth Worker from the Evangelical Church.
I expected the usual diseases, pregnancy and suchlike from them - what I didn't expect was that the diagram of the outer parts of a woman would be quite so heavily edited. It had urethra, vagina and anus - but not only were there no labia, the clitoris had also literally been masked off by paper and then the sheet had been photocopied, so they had deliberately chosen to take away most of the information relating to female biology (and without intending to I hope therefore made it impossible for any girl at risk of or having experienced FGM to know what was actually normal).
