Calorie burn in sex (Adult humour, text only)

slicksps

I was just interested as in a silly moment I found that 'semen' is actually in MFP's database, while sex doesn't appear to be. It is of course one of the best workouts (depending on position) and is definitely the easiest way to burn some extra calories.

Anyway, in my search I found this and nearly wet myself: http://www.c4vct.com/kym/humor/csex.htm

It's text only, not too crude but still over 18s only please.
