Oh the not trying thing is so true. This is an excerpt form the Sex Ed book we gave our kids (the one that got me into trouble with the school bus driver who reported me to the police.....)
Pay particular attention to step three. To see all possible positions, you need to buy the book.
Over here it's called Mommy laid an Egg. it's by Babette Cole and I wouldn't be surprised if the best pages were censored!
