I (editor note: thanks Steve for your honesty and willingness to share your experience, haha) once took a sex-education class in college and a funny thing happened one day.
The professor arrived and said we'd be discussing positions that day and asked us how many positions did we know. I sat there too embarrassed to speak but one gal a couple of seats over said, "Twelve."
The professor nodded approval but as he got ready to call on another student, there was a loud call from the far back row of the 150 seat auditorium, "A hundred and one."
The little professor looked over his thick glasses but couldn't make out who had spoken. Finally he called on a fellow down in the front row who replied, "Seven."
And once again from the very back was heard, "A hundred and one."
Finally he called on a very shy lady sitting next to me. At first she acted like she wasn't going to answer.
Finally she said, "Only one, sir."
And the professor said, "Well young lady that is unusual. And what position would that be?"
"With the man on top and woman on the bottom," she replied.
From the back of the room came that same voice, "A hundred and two!
