If I remember well, the dice lists:
- mouth
- penis
- hand and fingers
- anus
- vulva
- "an object"
No clitoris, no nipples.
... Does that sound like good sex?
what exactly is it teaching, and for whose benefit?
Does it come with a graphic description of the long term consequences of anal injuries? Don't think so (and lubrication won't prevent them: if it's too big, it's too big!)
Sex ed in my days was about avoiding STDs and pregnancy, not training to become an (anally incontinent) porn star.
There's also the fact this game is, in itself, by it's nature and focus, a sex act. It is, literally, foreplay: let's be playful, talk dirty, visualise what bit could go into what bit, explore our thoughts and feelings on the topic, and describe them to each other. In a classroom. As a group. Under the instructions of an adult. So much for consent... And so much for safeguarding.
There's a reason sex ed is typically "clinical", and not pornographic, in its language and focus. Talking about sex in a pornographic way is sex already: it turns people on (or grosses them out).
Do we want teachers and children to mutually turn each other on? (Ewwwww)
Or is the purpose to gross the kids out? And train them to ignore their own sense of disgust and personal boundaries, under peer pressure? Sounds healthy... (Not!)
