We got "The Talk" in 9th grade. The girls' gym teacher took the girls off to one room and the boys' gym teacher took them off to another. "The Talk" consisted of very little practical knowledge or advice.
One thing I'll never forget was the teacher telling us that boys just couldn't help thinking about sex all the time because their sex organs were out there where they could see them and be reminded. This, apparently, made them 24-hour-a-day raging sex maniacs. We girls, on the other hand, had ours neatly tucked away and didn't have to think about them all the time. Thus, it was up to WE GIRLS to keep things under control.
Then we got to watch a lovely movie, very graphic, about venereal diseases.
One of my friends, who went to a convent school, was told never to go with a boy to a restaurant that had white tablecloths because as he sat across from you at the table, he would be thinking about beds. I guess the secret there was for mothers of boys to only have pink or blue or flowered sheets, so the boys won't be triggered by white tablecloths...LOL.
Anyway, after finding out that boys think about sex constantly, I couldn't look a guy in the eye because WHAT IF HE WAS THINKING ABOUT WANTING TO HAVE SEX WITH ME???? Of course, I had nothing to worry about. Frizzy hair, teenage acne, braces on my teeth, ugly glasses and a figure like a board, I doubt any of them were fantasizing about me in particular.
It's a wonder any of us ever moved on to actually....doing IT.
