I used to believe that a "blow job" meant that the man lay down on a table naked, and the woman literally "blew" on his penis until who knows what happened.
I also believed that "getting laid" had something to do with a very clean table with a white sheet over it. The man and woman would both take off their clothes and lie down side by side on this flat, clean table. I dared not think past that point.
I was not a little child when I believed these things. I was about 12 and learned these terms from the wild Irish girl who used to sit next to me in French class.
