I always thought that when a man and woman wanted to 'make a baby', their nipples had to be aligned as well as their nether regions!!
I just couldn't figure out what you would do if you were smaller than your boyfriend/husband!!!!
A childhood belief about sex

others believed things like this
- That to make a baby a man (over 21 & under 25) had to kiss a woman (over 19 & under 21).— Johny
- I thought that a woman got pregnant kind of like catching a cold, by being around her husband for a long time.— No Name
- My niece believed that the longer I breastfed my baby the smaller my boobs would get. She was 4 at the time.— M
- I used to believe that wearing a bra that was too small would make my boobs get smaller.— Aretia
- I used to think that if a black woman or man and a white woman or man had a baby, it would be Asian.Anon
- I used to think Hannah Barbera was one woman...not two men. I didn't figure it out until I was about 15!— minkie
