Watched a couple of episodes of Sex Education on Netflix this weekend as well. It was better than expected, although I still felt uneasy watching high school kids have sex, even though they probably are all over 18 in real life, or at least the ones that are showing nudity.
Yeah, the British started getting really comfortable with shows about teens having sex a long time ago. I remember "Skins" getting a ton of attention for showing students having sex, doing drugs, getting raped, and so on. It seems to me, at least from their TV shows, the British and Irish cultures are comfortable discussing and showing youths having sex.
