Honestly, this is disgusting. I'm not being a conservative kink-shaming prude about this, but did anyone really ask "who was that for?"
In all fairness porn-addiction and access to porn is an issue for children of that age. And they do have issues trying to make sense of what they see half the time. But instead of going with that flow of explaining those kinks, maybe the nurse should be helping kids analyze between reality and fiction better, before teaching them about 'consent'. If you explain away all the kinks in those cards, you'll still have to find a partner willing to do them. I doubt the nurse is explaining that caveat to the kids, who may not find such kinks appealing to them.
