See, I'm all for the gradual process. I'm all for learning about one's own body changes. I just can't wrap my head around the other stuff.
From my experience, learning sex ed in two high schools (one a fancy all-girls and the other a mixed, low SES), sex ed was so inappropriate, from my POV as a 13/14 year old. So many kids just couldn't wait for it, like it was some sort of porn. Many started having sex shortly thereafter. Many girls got pregnant. Ugh. Looking back, I personally wish that sex ed wasn't taught until the endoff high school.
Talking about body changes, like puberty, is different. That can probably be taught from age 10, in segregated groups. But, IMO, sex and its "accessories" can wait.
Not when the kids are starting to have sex or experiment sexually from ages of 10 already. The international average age is still set at 15 years (last time I checked), but it's decreasing.
If my kids were at school I would not wait till they heard about it from a teacher or a classmate in the playground.
