Did your elementary school library have a hand-written note on the inside cover that read: Go to page 147.
And a note on page 147 that read: Go to page 489.
Ect., etc., etc. Until after going back and forth to 20 assorted pages with directions to the next page your final destination was the page that contained the definition for the word bitch?
I once read an old transcript of a Saturday Night Live which featured a bunch of pre-teens at a slumber party (Gilda Radnor, Jane Curtain, Lorraine Neuman and Madelaine Kahn) and Madelaine had just told the girls how babies were made. One of them said, “My parents have SIX KIDS!!!”
“Father, why do these words all sound so nasty?” 
I was young enough that they weren’t putting dirty words into dictionaries yet.
I will say, however, that when my mother gave me some article to read by way of explaining the facts of life, I looked at her in astonishment, and said, “But that’s fucking!”
I knew everything about sex except that it was involved in reproduction.
Fart - n. Anal expulsion of intestinal gas.
Don’t think I’ll ever forget that. I had to have been in the first grade in the school library.
I was 7 when I learned that fuck was an exciting and fun word that made other kids giggle and snigger. It was a good month later before I learned that it meant anything.
I was 7 when my mom told me my first dirty joke -
Q: How do you get an elephant off the ceiling?
A: Jerk him off.
I had no idea what it meant. When I got my own unabridged dictionary at 10, I immediately looked up “the c word,” because I heard two older girls use it outside once. And because my mom’s friend once used “C-U-blank-blank” in Scrabble. I also looked up “tit,” which meant a small or inferior horse, so I could walk around the house saying “Tit! Tit!”
My mom also likes to tell the story of how, when I was 9, I was at the library looking up information on the Egyptian pharoah Mycerinos for a school report when I saw an unfamiliar word in the encyclopedia. And asked her, out loud, in the children’s room, what “masturbate” meant. She told me to read the definition, which I think was something like “to prepare one’s self for sexual activity.” Which only confused me more, since I knew by then that it had to do with the difference between boys and girls, but I had no idea what that actually meant. Taking a bubble bath so you’d smell nice?
When were you in the sixth grade? Was it anytime in the last century?
I was looking up dirty words in German, Italian, French, Hebrew , and Russian before you were born.
Well, not exactly Hebrew, but Yiddish.
It must have been 6th grade, I’m thinking. My 5th grade teacher made me write out sets of multiplication tables as punishment, and heaven knows why I decided it was easier to write out numerous sets of multiplication tables than to do my damn homework.
Anyway, as punishment for some schoolroom violation or another, a teacher ordered me to write out 50 definitions. I was at home, going through the dictionary (no punishment at all, as I read the dictionary for fun), and writing out definitions for various interesting words (which was punishment, because hello–writer’s cramp!). A friend came over and wanted met to go outside and play, but I told her I couldn’t until I finished the assignment. I don’t recall if I thought of it first or if she did, but for the last 15 or so definitions, I wrote down every dirty word I could think of and then looked up the definitions. IIRC, if a particular word wasn’t in the dictionary, I made up my own definition.
Boy, was my butt red and tender for at least a week after that!
I think I was in college before I thought to do that. Yeah, I was kind of a late bloomer.
