I used to think that oral sex was when people were kissing, one of them would reach their tounge into the other person's mouth, and touch some special little "button" and that would give them the same feeling that intercourse would. And I thought that maybe if you both touch each other's "button" at the same time, the woman had a good chance of getting pregnant.
This was all in 7th grade, mind you.
