We had it first when I was in 6th grade in biology. This was mostly here are your reproductive organs and here is what happens when you reproduce.
Second time was in 8th grade, here we had once again everything we had in primary school + a little more in-deph + including a little bit genetics & sexuall illnesses.
That year we also had a talk about consent, birth controll and struggles of teen pregnancy in houskeeping class.
Later that year we had STD prevention week, where they explained every known STD and their symptoms including images of the sympthoms+ showed interviews with people afected and the history of the STDs and how they are treated ect. (That was scary AF, but hey we got free condoms)
Later I moved to the Gymnasium and we had it once again but mostly focusing on genetics.
Edit: this is where I lived in Switzerland and not for the whole country as in Switzetland every Kanton has their own school ecosystem)
