.... she was more-or-less like what you have between your legs is called a vagina and what a boy has is a penis. And the girls body make eggs (but not like what chickens make) and boys make sperm (she didn't explain what that was then) and when he puts his penis in a vagina that makes a baby.
How many of us can remember when we got the Birds and Bees lecture. I have a very vivid memory. I was 12 and I was outside our house, cutting some kindling for our wood stove.
My dad, a man of few words came out and ask me. "Do you know babies come from?"
I replied "Yes."
He then said, "Just be careful where you put that thing."
Words of Wisdom that I still follow 70 years later.
But being 30 years old already, I knew most of what was in there.
What really sucked was no pictures, just stickman diagrams.
Only message my dad told me was when I was about sixteen years old and getting serous with a young lady. He had just learned that his secretary's son had gotten a girl pregnant and was getting married at an early age. He simply told me: "Just keep that thing in your pants". Oh, what wonderful advice from someone who should have known better.
...where babies come from? I must have been out that day.
My parents never had the "talk" with me. I stumbled through somehow. They were both great. I'm thankful for them everyday but that's one place they weren't going to go.
With the amount of sexual info available, I think today's 12 year olds could give their grandparents the "lecture."
A dad sits down with his 12 year old son and says: "Son, I need to discuss the whole subject of sex with you."
So, the son replies: "OK dad, tell me what you want to know it."
By the way, my generation told our children all about the mechanics by the time they were 5, and they would proudly repeated all this to any person in the room who would listen. Of course they had no idea of the real impact of the knowledge. It was as if we had just explained how an internal combustion engine works.
How they actually ended up with the real impact I'll never know, and I think I don't want to know either.
...that my mother told my father it was his job. And he chickened out. Gave me instead a book on the life of eskimos, which turned out to have some explicit descriptions of their society & life.
Maybe that explains why I get so excited about ice floes 
not sure where his info started, but I was there all ears and watching. he told me all about ejaculating and I then tried my hardest to do it too. finally one day did, was so elated and proud.
...and he successfully told me about the importance of protection!
But he also told me that oral sex was perverted. Boy, have I ever become a pervert!!! lol
Spent my early youth in the third world, and our family had servants. I was friends with the cook's daughter. I was about 8 at the time, and she said one day, "They's mating the dogs, lets go see." So we went out back behind the outbuildings and sure enough the dogs we fucking., surrounded by a bunch of guys from the neighborhood. Now she was a farm girl, so she was explaining everything that was happening to me. Later in the day, she got it in her mind to try fucking, so off we went to the bedroom that she shared with her mom. Now, at the tender age of 8, I was not getting it up, but we were too naive to actually figure out what we were doing wrong, all we knew was that it wasn't going in like it was supposed to, so we gave up. That was the beginning of a really long dry spell!

That reminds me. Even though I knew where babies came from when my dad ask me. I hadn't actually ever utilized that knowledge. Next door 2 younger girls and a brother lived. The brother and I decided to see if we could practice with them. They were interested but wouldn't put out. I think it could have been my pick up line. "let's touch pee pees" Whaddayathink? lol
Got it from mom. She told me get her pregnant an your taking care of her
I was always disobedient. Dad told me to stay away from prostitutes. Hmmmm...

When my 2 kids were 4 and 6 we were in Kenya. I was doing a research project that involved butchering various mammals and recording reproductive status. I did this in the field while on safari. My family was with me. The kids were curious and I was able to show them the reproductive organs and how the male and females differed and how they worked.The females were in different stages of pregnancy and I could show the kids how reproduction worked. A few years later my wife and I discussed the social aspects of reproductive activity.
I imagine kids who live on a farm with livestock probably learn the facts of life earlier than city kids in those days many years ago
