As far as I can see, and I don't mean to be too crass about it, there's been nothing new in the pole-in-the-hole game at least since the time of Caligula.
Nevertheless, Departments of Education, School Boards, etc, feel obliged to offer up "new" sex education curricula every few years.
The latest manifestation of this tendency is currently on display right here in Ontario.
Oh ya, it's CONTROVERSIAL according to the news media.
Nothing like a controversial sex-ed curriculum to goose viewership!
Apparently it's controversial because it talks about wanking and anal sex.
Well, that's not new. See Caligula above.
Even the Bible references that wanker Onan spilling his seed on the ground...
Nothing new about that!
As for the anal sex bit, ya, a utilitarian may be tempted to deem a hole a hole, but we have biblical antecedents to that proclivity as well; google Sodom.
Nothing new there either.
Apparently what IS new is the discussion about cyber sex and all its derivatives; cyber dating, cyber stalking, sexting...
But that's not about sex, it's about technology. That should be part of the technology curriculum.
Here's the real reason we need a new sex ed curriculum every few years; it makes oodles and oodles of work for educational consultants!
Now, not to put too fine a point on it, but generally speaking, the "educational consultant" cohort were teachers at one time, teachers who realized that they hated students. Teachers who decided to work their way up. Teachers who realized that they would much rather spend their working days liaising with other educators than actually teaching yucky students.
And if you're going to spend your working life liaising, what more juicy a topic to liaise over than sex education!
Think about it!
Endless round tables and focus groups and study sessions on how deep to go into anal sex... masturbation... oral sex...
Hell, no wonder it takes years to come up with a new curriculum!
