When I was 16 and in my junior year of high school we took a trip to VT over Thanksgiving break (which we did every year) and along the way we stopped at this local restaurant for dinner. And it was pretty slow that night so my parents, brothers, and I were chatting with our waitress and my dad asked about the history of the town and we find out that the building the restaurant was in was once a brothel.
Now I don't know exactly how the exchange went, but somehow I said something to the tune of "what kinds of soup did they make?" And everybody stops and looks at me all weird and I'm like, "what? Isn't a brothel where you make soup?" and explained my reasoning for thinking that was that broth was a type of soup and so a brothel must have been an old timey soup factory. And my dad chuckled and pulled me close and said "honey please stay innocent forever"
And that's how I found out what a brothel really was.
For background I was always a bit naive and I was also quite sheltered, so I just never heard of a brothel before.
I used to believe that the number of children a married couple had was the number of times they had sex. A family with 12 children lived in our neighborhood so I thought their mother and father were very sexy.
I used to think "premature ejaculation" was a boy ejaculating before he hit puberty.
I used to think prostitutes were women who had taken too many contraception pills, because of the fact that it's often associated with drugs.
For my whole childhood, I thought that lesbians could only do handjobs.
When I was four years old, I used to believe that the previous sister or brother can choose the gender of next child in family.
My mum allaways asks:
"A brother or a sister, which do you prefer? "
My sister said she wants a girl and I borned.
I said I want a boy and my brother borned.
So I used to believe this theory very much.
When I learned that prostitutes were women who sold themselves to men, I pictured them sit in shop windows, like mannequins, and being pushed around in trolleys.
When I was learning about stranger danger, people were so vague with descriptions like "saying things that make you uncomfortable", "touching you in a way that makes you uncomfortable", and "talking about sex" that I thought that:
A) Any stranger who accidentally scared you or tried to hug you when you didn't want a hug, etc was bad news, and...
B) It was illegal to tell a child how babies were made unless you were their parent or teacher.
I learnt about genetics when I was, like, nine, but didn't learn about porn until way later, so I used to think that if something was X-rated, it was for women (which was why a little boy might get in trouble watching an X-rated movie).
Up until very recently, I thought "S&M" stood for "Scully & Mulder".
When I was at intermediate age, I thought the penis and vagina when I had puberty classes back in the day were a puzzle. Connecting one piece to another. When I grew up at college I knew that sex was a thing that parents do when they get married. I now know that God has made sex a beautiful thing between a husband and wife.
I am a male-to-female transgender. When I was a boy, I felt mostly like a girl, and I thought everyone was tricking me into thinking I was a boy because my mother wanted a son instead of a daughter. I thought this was the reason of why my hair grew so fast (I thought this was why girls usually have longer hair) and that everyone was born with a penis, but in women it disappeared during teenage. Saddly, I grew up and was proven wrong...
I thought that sex was when two people put on the same pair of pants, one person in each leg. Needless to say, weight loss commercials were absolutely scandalous.
So when I was a kind, any time something sexual happened in a movie or tv show they would play that jazzy saxophone music. So my brain just associated the sound of a jazzy saxophone with sex and any time a song got jazzy I would blush and get embarrassed and say the song was nasty and to turn it off because that's how my mom acted when something sexual happened in a movie. Weird right? I still get weirdly uncomfortable when I hear a saxophone getting jazzy.
This is more of my understanding of relationships than anything sexual. For the longest time I really thought that cheating wasn't possible. I thought it simply didn't happen, that no one ever pursued two people at once. But then I learned that people do that and it felt so weird. I couldn't wrap my head around it. Why would you need two people? To this day, I can't ever see myself cheating or understand why people do that.
Okay so this is more about sexuality in general than any particular part of sex. I am and always have been a bisexual and when I was little I thought everyone was. I thought it was really a common thing. That we could all have crushes on both genders but there was some kind of secret deal that society had made, that we'd all keep those feelings of love and attraction for same sex a secret because it didn't make babies. I thought everyone just ignored their feelings for people of the same gender because we all wanted to have kids when we were older. But I didn't mind the idea of not having kids so I told a girl I liked her. She told everyone and they made fun of me, but that only encouraged the theory that they were all hiding the same thing and they were just mad that I wasn't following their rules. Because of this, and the fact that I was bullied so much for it, I decided I would follow those rules and I pushed all those feelings I had for girls deep down inside. It wasn't until I was eighteen that I finally came out of the closet and accepted my feelings for same sex. To this day, I still feel embarrassed when I find myself attracted to a beautiful woman.
We had these cheap anatomy books that had always sat on the bookshelves. I once dug through them at 6-8 and read through (or stared at thr pictures) the whole chapter on reproduction, pregnancy, the whole nine yards. I was young and NONE OF IT made sense to me. I did however come to believe that Organisms were big living things and Orgasms were smaller living things. I still looked at those words that way for the majority of my childhood...
As a young girl who grew up with brothers, I of course saw them take a bath or get a diaper change, so I knew they had different genitals right off the bat. When my mom became pregnant, she also explained, very vaguely, that it took a boy and a girl to make a baby and then mommy carried it in her tummy until it was ready to be born. You'd think that would tell me enough to put two and two together and figure out the actual act but for years I didn't have a clue. I knew it took a penis and a vagina, but as far as I knew, neither of those parts could do anything but pee. I didn't know about erections, or that my body was supposed to fit anything inside it, so I figured that when a girl and boy were ready to have a baby, they got naked, they snuggled and then the boy peed on her. Hey I was pretty darn close if you think about it!
I used to believe that sex was only done in the hospital, and doctors would watch as the couple had sex. I believed this until I was 13.
When I was little I thought girls had "man parts" as well, but it just took longer for them to grow.
