My older sister and I found my dad's secret stash of "girlie" magazines one day. One picture portrayed a man with his penis in the woman's mouth, while another portrayed a woman with her mouth on another woman's wet-looking lower extremities.

It was a long time before I realized that they weren't allowing other people to pee in their mouths. (Boy was I disgusted at first.)

I used to believe that "rape" was "rake", and that if you got raped, some big scary guy stood over you and raked you with a rake.

When I was in kindergarden I used to believe that sex what when a man and a woman would dance together nude in the night.

When I was little I saw that my mom had some lacy underwear. I figured that it must be so that the man's semen could go through the lace without them having to have intercourse. I thought it was for people who wanted to have a baby but didn't want to have sex. I didn't understand why anyone would wear something as uncomfortable and itchy as lace next to their private parts.

When I was little, I used to think that Lesbians were people from some country called Lesbia.

After a friend had shown me his older brothers dirty mag of a couple making love on a table i believed this was the only way of having sex, proberly something to do with the angles i thought.Mealtimes at our house where always greeted with a sense of foreboding.

When I heard my brother describe a man and woman's reproductive organs as the hot dog and the bun, I developed a picture in my mind that that's how a man and a woman had sex: The man's penis would just lay on the outside of the woman, like a hot dog in a bun.

my friend used to believe that a dominatrix was a person who dominated or was in charge of Trix cereal, like they got to pick the colors and flavors and shapes that went in every box. she was very perplexed when i disillusioned her.

Another kid once confidently told me that a couple had to have sex in order to have children only if they wanted their offspring to resemble them.

When my mum had 'the talk' with me she explained everything well. But when my Dad came to have 'the talk' with my younger brother a few years later, he decided to take it a step further, explaining that when a man has sex it's like a volcano erupting. My poor brother! I'm not sure if it's put him off sex for life or not!

I guess I was about 10 or 11... anyway, whenever my best friend came over and spent the night she would make us watch pornographic movies late at night. I didn't know very much about sex at the time, so during the movies I would constantly get up and go to the bathroom, only to find out that it wouldn't come out. I finally told my friend, "Whenever we watch these movies I always have to go pee, but it doesn't come out". She replied by telling me that I was "getting horny". (This is strange because she was a year younger than me...)

That's not all. A few weeks later I had the urge to go to the bathroom, but nothing would come out. My mom was in the bathroom with me at the time, so I said "Mom, nothing's coming out. I must be horny". The look on her face was priceless... needless to say, she asked me where I heard that phrase and what I thought it meant, and she set me straight right there... (But she didn't know that me and my friend had watched those movies ;P)

When I was little I used to believe that There were Three ways to have sex. Fully clothed, partially clothed and completly naked...
Only certain people could have sex one of the ways but no other way and that the first time you attempted to have sex you would figure out which way you were.
I also believed that if you had sex differently than another person, you couldnt have sex with that particular person....

I used to think that gay men had sex by facing each other standing up and butting the tips of their penises together.

No, don't think I'll put my name on that one.

I thought women could only get pregnant if they were married, I think I actually believed this until I was about 10.
At about this time when some girls at school started telling me about what happened in sex, because their mums had told them about it, and my mum hadn't, I thought they were joking and asked if the two people had to be tied together with ropes or something to keep them in position because I could just not imagine how people's parts of the body could go together! I did not believe it for a long time, probably until I was about 12. I still feel silly about that question I asked the other girls and I think they thought I was pretty stupid.

When I was a kid, I thought "rape" meant removing one's sandals in public, usually in a public park.

A classmate in fourth grade claimed "pewter" meant a man placing his penis in a woman's breast, and I and the rest of my class believed it. Our teacher was baffled whenever her references to ancient pewter artifacts were greeted by giggles.

at junior school i was told by my friend?? that gays were called 'bummers' because they rubbed their bums against each other bums.

i used to think that "making love" was two people getting naked & drawing a heart...if they decided they wanted a baby they would send thier heart to the stork.

Because my parents would always turn the channel or remove me from the room if a sex scene ever came on T.V., I thought that sex was this awful thing that my parents were trying to keep out of the house. I thought that if you had sex, you would go to hell. Then one day, I accidentally walked in on my parents having sex, and I was so convinced that they were going to hell that I cried for hours. My mom decided to have "the sex talk" with me at somewhat of a young age because of this. I now have a baby of my own, and I plan on taking a different approach.

Lacking a strong religious background, I somehow convinced myself that "adultery" was the same thing as sex. I couldn't understand how Mormon people could adhere to the 10 commandments and still have so many children if they weren't allowed to have sex. To help explain this dilemma, I decided that the man must ejaculate into a syringe (no needle attached) and squirt it into the woman's vagina. Sexxxay.
