BigMouth
Big Mouth is a raunchy, adults-only animated comedy on Netflix. It's about some children, middle-schoolers, and their experiences with puberty, sex drives, menstruation, and other things to do with growing up. It's my competitor because it's also sex education. (Just kidding, it's not my competitor.)
Big Mouth has a lot of crudity and nudity and I don't recommend it for children or even teenagers. But, if you hate my sex education website, and don't mind gratuitous nudity, I think you're much better off watching this show than getting no sex education (or getting it only from porn). I actually watch the show partly to keep up on sex education in society and partly because I enjoy it, but I'm 45 and I still find some of it way too gross.
It has some good points, it's generally accurate about the pains of growing up and about sexuality and bodies. I think it's mostly honest. It even has an Aesop that looking at internet porn is addictive and probably not a good idea. I don't like The Planned Parenthood Episode, which tries to pretend that killing babies is healthcare.
