You know, I haven't seen all of it, but I always had the impression that Big Mouth was specifically made not for teens or children, but that it was more cringe-comedy for adults where we could look back at our awkward teenage years when we were coming into maturity but not really knowing what to do with it. I actually liked it for the most part (some of the jokes were a little too gross for me), but I honestly never thought that it would be a thing that teens or kids would watch. That was probably pretty naive of me, considering it's an animated show.

I can't imagine someone using Big Mouth as sex education.
