I found this a very concerning read. 8 year olds being required to look at nude photos of adults, and a detailed illustration of a vulva, and to discuss their feelings about bodies large and small. Also "interesting" that the male nude has been photoshopped to have long hair.
Apparently children are showing real discomfort at the content and some teachers are refusing to teach it.
