When I was in fifth grade our first day of sex ed was just talking about deodorant and stuff. And, because it was elementary school we expected it to be. well looking back I don't really know but it wasn't just deodorant. Point is, at the end of class everyone's going oh wow, that wasn't that bad until the teacher goes all right all right everyone, one last thing, penis. then entire class started laughing. Beyond that it was mostly cringy videos of kids telling us about how puberty is fun (something they actually said).
