Sex Education should not be lumped in with Euphoria as it is actually very aware of the diversity of sexual and asexual experience and is very validating of asexuality.
Yes it depicts "most" teens as being horny because well, they are. Most teenagers are horny, that's a fact. Asexuality is not the norm and that's ok.
But it doesn't depict everyone as being "experienced" and does a good job in actually showing the diverse spectrum of sexuality (including asexuality) between people of all genders and includes neurodivergence as part of it as well.
