Maybe if they saw what that sort of lesson plan looks like maybe they would realize it’s hardly as lude as people make it seem. Basically the key points are
Anal / Oral sex exists
These forms of sex comes with unique disease transmission risks.
There are specific condoms that offer greater protection for anal sex
Safe preparation before hand involves a cleaning stage and the use of lubricant
If you are female you have a much higher risk of injury
That’s really it. It’s hardly sitting kids down and getting them to watch porn, heck you don’t even need graphics. Honestly if we mustered up a national program to put adults through actually decent sex ed so they wouldn’t freak out so bloody much we wouldn’t be having this problem. Where I am when I was a kid they piloted a number of university lecturers to hold age appropriate sex ed starting at grade one which covered basic anatomy and consent. They realized that just giving girls particularly exact words meant way greater protection for them as when a little girl comes to you an goes “My uncle touched my cookie.” doesn’t immediately ring alarm bells.
I would hazard that if they put it to a vote actually attending programs like these should be mandatory for actually getting a say. Letting the ignorant and uninformed decide the quality of an education system can only lead to it being subpar.
