Sex Ed should probably stay away from schools, especially in the modern era of faggots and trannies and niggers. Your parents should tell you about it or you should really discover it yourself, like most kids do. If you know how to masturbate, you'll know how to fuck eventually. It's a bit weird to talk about but at a certain age you kind of just have to let them get curious instead of forcing it down their throat in a way that's honestly kind of cringe. I remember one of my teachers trying to describe masturbation and he did a really shit job at it, he was saying "one day white cream will come out of your pp and it will be totally normal"
It's a hard topic, but I do think we could use like a dating ed or perhaps more lessons for how to navigate social situations and make friends and stuff like that, but I'm an autist and thats why I would require that specifically. But honestly as far as sex ed goes, you kind of just have to figure it out for yourself, everyone does, basically.
