I used to believe that a man had as many testicles as he had children. So I thought the Catholic guy next door had nine balls and that I'd only have two kids when I grew up.

In 4th grade we were discussing what type of jobs we wanted to pursue. Using a term I somehow learned from my brother, but having no clue what it meant, I remarked to my friend that I wanted a blowjob. The teacher overheard and wasn't so happy. I got a nice lecture in the hall.
I thought when i had my period that i was dying, my mum never told me what it was
I used to believe your glans can fall of your penis when you pull down the foreskin (I'm not circumsized).
when i was little i thought that when a lady gave birth she had the baby thorugh her belly button!
When I was little I used to think that babies came out of the bum hole.
lol what did I know
When I was 5 I used to think that boys and girls both had the same thing until a friend proved otherwise.
hey I was only 5
I believed that a condom had to be used wile kissing eachother the french way. so you put the condom in your mouth and you kiss on the mouth and the condom prevents that aids will be exchanged by the mouthfluids.
I think I believed this because I saw a show on tv where they talked about the condom while they showed a kissing couple

I believed when I was really little, that if you went into Mothercare you would become pregnant.
The urban legend of the school nurse! It seems quite universal and had many others confirmed that they had the same belief in school. At a certan grade in school, 5 I think, the class would line up for a private inspection by the school nurse. It was rumoured that she would weigh our testicles with a cold metal spoon. And if you got an erection she would deflate it by pricking it with a pin. When the time came for the visit there were alot of nervous little faces lined up outside the office. Strangely enough when it came to the second inspection in high school, the same rumours went around and the faces certainly did not look any less nervous lined up outside the office.
When my brother was still much younger, he used to like going through my things. One day he came across a box of tampons and wanted to know what it was used for. Embarassed (because he asked this infront of some of my male friends), I explained to him that tampons were used in case of a nose bleed. He believed me then, but I think he knows all about it now. Luckily he never had any nose bleeds when I was around...
When i was small i didn't really know what tampons were for but i had a little idea. when my mates used to come over and play i used to soak them in water and chase my friends around the house with them. they would freak out and i would be having the time of my life.that is until my sister came home one day and saw me doing this. that was the end of the running tampon.
I used to believe that condoms were devices that elderly men donned, before enjoying a few pints at the pub, to soak up any urine leakage.
That was because my dad told me so.
My mom used to tell my brother that if he ate too fast, his appendix would burst. I thought she was talking about his penis, so every time she said that I imagined my brother having the anatomy of a Ken doll -- that is, no "parts" whatsoever.
I can still remember my Dad shouting at my brother to hide his porno mags properly in his bedroom and get rid of those dirty "french letters" (condoms). I spent ages trying to figure out who was writing to my brother from France !

When I was young I always believed that big pink rubber bag was for placing on your stomach when you had a upset stomach....later I was told it was a Douchbag!
When my best friend first explained sex to me in 5th grade I misunderstood and thought that instead of the man ejaculating to make the women pregnant that he just urinated.

I used to believe that just like guys getting erections girls asses would get all hard. I don't know why, but I belived it.
I was once so naive that I thought that condoms were the male equivilent of tampons as although my Mum told me about periods, she never said men didn't get them either! So when the girl I used to sit by in English at age 11 said she would do it with Ayrton Senna as long as he wore a johnny I was absolutely appalled at the thought.

i used to believe that couples could choose their children at this big, special place.
