My grandchildren, boy now 11 and girl now 15, both attend online school and at age 9 and 10 had PHSE lessons Personal, Social, Health and Economic education. I was able to hear these lessons. They were age appropriate about relationships and a good introduction to sexual health and hygiene. Frank class discussions, basic introduction to sexual relationships both straight and gay. No mention of transgender or identifying as anything other than male and female and no anal sex. The kids felt free to discuss anything with their mother and I. My grandson now has a best friend who identifies as "they" and understands that this is accepted by the boys parents but is not influenced by him. Sex education can be taught sensitively
