A good friend of mine forwarded this site to me. It is hilarious. People write in and tell what they used to believe when they were children. For use in this blog, they have sections on sex and pregnancy. Here are some examples:

I used to believe that boys had boy babies, and girls had girl babies.

That was when I was 3-7. I'm 15 now.

I used to believe that if a pregnant woman had a bump out the front she would have only one child. Twins meant bumps out both sides. Side bumps and a front bump was going to be triplets. Quads would have been very uncomfortable with bumps in four directions. More than 4 bumps (babies) I couldn't even begin to think about.

When I was about 5 my mom was pregnant with my sister and I asked her "how do you get pregnant?" After a few seconds of her going "um...uh..." she finally told me, "you have to dream it!" So up until I was 12 I thought that the mom and the dad both had to have the same dream at the same time that they took an elevator up to heaven and told God that they wanted to have a baby. Of course now I know better.

my mother told me about the birds and bees and said that I should be careful because sperm can go through anything and get me pregnant. Everytime I went to bed I was afraid there was a guy under the bed and the sperm would make it through the bed and I would be pregnant.
I was so afraid to go to sleep and would only sleep on my side. Making it harder to get to me.

When I was younger, my mom gave me a book on "Your Body Changing". It wasn't the best written book, and I thought that you could only have a baby if a woman was starting her period. I thought that that was a logical explination for why some couple had trouble having a baby.

When I was really young I thought that you bought a baby kit from a department store like Penny's, because my mom told me that she had bought my baby stuff at Target.
