I also have a copy of the book. There is no mention of fisting whatsoever. I suggest you ask Mumsnet HQ to take down your misleading post as it's simply untrue that a book about fisting is on the Irish school curriculum.
The more prosaic truth is a relatively explicit book was suggested to teachers but has now been recategorised as unsuitable for a younger age group. Meanwhile, a group of anti-migrants and anti-vaxxers have lied and said it includes material on anal fist-pumping (whatever that is).
Of course if you prefer not to find out the truth yourself by actually reading the book then go for it, but do stop spreading lies.
