To comment on @Nurse_Phillips tome.
The actual vagina isn't visible unless you pull the vulva open in 90%+ of women. When you see her genitalia, you're looking at her vulva. The word 'vulva' comes from the Latin word for 'wrapper' and specifically describes the folds while 'vagina' from the Latin for sheath - ie the receptacle for a sword.
It's nice to learn those origins. I've never thought of it as a wrapper maybe because I never thought of my penis as a sword, more like a thumb tack.
Look at early 20th Century attitudes to women's sexuality -
This makes me think of an old B&W movie I saw years ago. My first job after High School was working swing shift in a cotton mill and I wasn't ready to sleep when I got home at midnight so I watched TV. It may have been a W C Fields movie where he was getting ready to go out and the scene shifted to the kitchen where a young wife was helping an old(er) one wash dishes. She complained that her young husband expected sex and the old one told her it was her duty as a wife to do that. I was thinking if that's how women really feel I'd rather just use my hand and the hell with marriage.
Because the vast majority of people who made decisions on sexual education etc were men,
I've never felt it had to do with MEN per se, In my house it's my wife who is vehemently against sex ed in schools or any where else. I am just as much FOR it as she is against it which creates some interesting discussions in our house. I wish we had some of the ones I've see on Channel 4 from the UK and from Norway.
Why do you think that damned few people even knew what a clitoris was? I certainly didn't, and I've got one!
Don't get me going on that!! I certainly didn't either, exactly at the time I needed to most. I had heard that girls had a spot that would give them a pleasure sort of like what us guys got at the tip of our penis but nobody I asked could tell me how to find it or how to make it work. When I was 19 in the army my 16 year old gf certainly knew how to make mine work and when it quit she shoved my face between her legs but I had no idea how to find what I was supposed to be licking. I had no idea if I should be able to notice any response. I even asked the wife of one of my friends where and what and how I could tell if she was having any pleasure like mine (didn't know of the word orgasm). All she could tell me was she liked the feeling of him inside her but no wild and wonderful feelings, and they'd had two kids already.
It harkens back to the days when female sexual pleasure was dirty. I recall a book from the early 1900s that was supposed to be a version of 'you're growing up' now for women that warned against women having sex with their husbands too often as it would destroy their marriage and that women who succumbed to actually enjoying sex would meet a bad end. Unfortunately I lost the book in the divorce - not through any official settlement but along with a ton of other things I abandoned to get the fuck out of there.
I believe that. That's kind of like the crap I saw growing up, you know, the books I kept hidden inside my console radio cabinet.
By referring to a woman's vulva as a vagina you're invalidating her sexuality as nothing more than a receptacle for your penis or a machine for making babies.
I knew those guys, they were my classmates. Well, it wasn't a vagina, it was a cunt.
