My first sex ed was last year of primary school, it was all the boys from my year put into the IT room, the girls had the main hall (our IT room was probably no bigger than most of your living rooms btw so pretty cramped up for us) where we then watched a cartoon which had a duck blow bubbles off of a man and woman standing in a bath quacking then it narrating about whatever body piece he'd just blown bubbles off.
The sex consisted of these 2 people get into bed then zooming in to the quilt which had a cat design, more narration and these cats kept shrinking up and down next to each other like tweedle-dum and tweedle-dee then the narrator said she that the man put sperms in the woman and now they have a race to the finish.
In cartoon sex ed land, this seems to mean an Olympic style swimming race must be had towards the final line which has 'an egg'-like thing walking about all dolled up in make up, obviously an attempt to have some sort of 'Race girl' (you know what I mean)
Then babies, i think the rest of the thing before and after the duck bath was just these babies crawling around flicking and prodding each other and themselves
SonicSam could of directed something better
