The idea of needing sex ed in 2022 seems laughable. It made sense before the internet when you'd get some weird borderline-amish families that would never talk about sex or let kids watch tv or hang out with other kids so they'd have some fucked up retarded ideas of how reproduction worked. In this day and age you learn that shit through osmosis just from general culture. You have a natural interest in sex once you hit a certain age anyways so all the information is there. I did sex ed in like 2004 maybe and there was nothing I didn't already basically know.
Also I'm extremely suspect of male elementary school teachers. I'm sorry but that's just some weird shit. I remember we had this dorky male 7th grade teacher that looking back was very weird. Dude was never married, never in a relationship, LOVED Elmo (had teddybears of him all over his classroom) and his entire social life revolved around kids athletic events...none of which he coached. The Catholic church gets a bad rap but kids are way more likely to get abused in schools. 4% of catholic priests are abusers compared to 5%-7% of school teachers. This study suggests 10% of kids will experience sexual misconduct by school employees
