I actually missed late sex-ed and ultimately learned about physical sexual anatomy from Wikipedia as I was outside normal curriculum's due to autism.

As for your kids, my recommendation is to take effort to ideologically prepare them for any regressive leftist bullshit spewed out from the teacher.

My last English teacher promoted the Critical Theory type bullshit about media influence on culture along with Objectification Theory and how it all fuels toxic masculinity. He got what he deserved as I gave the teacher hell without even trying because of my autism.
