When I was in about second grade, my younger sister (in first grade) came up to me and asked if I knew what a blowjob was. Being the older sister, I couldn't tell her I'd never even heard of one so my response was naturally "Of course I do." Her: "Well, what is it?" Me: "I know what it is but what do YOU think it is." Her, after a moment: "It's when two people put their butts together and fart." Of course, being the super-smart older sister I agreed with her and we continued to play.
Some time later (months, years, who knows?) we were at my dad's house and my youngest sister (who was in school so this must have been a few years...which goes to show my level of naivete back then) is sitting on my dad's back and rubbing his shoulders when she farts. I innocently look up at her and dad and say "What are you trying to do, sis? Give Dad a blow job?"
I never saw my dad jump so high so fast. That was the weekend that I learned a blowjob was NOT related to farting, but I never did learn what it was until years later.
What are some of your funny/favorite sex (or lack of it) stories?
I remember one night my parents and my brothers were at a Pizza Hut. My Mom was trying to tell my Dad a "dirty joke" and she'd put her hand up and whisper "bj". Finally I got annoyed with her giving us side glances and saying "bj" that I said "can't you just call it blow job?" She was horrified. I was probably 11 or 12.
