I was 16 when I got a letter published in a UK national newspaper on this topic, pointing out the absurdity that deliberate murder could be shown in a cartoon aimed specifically at young kids (i.e. BBFC rating Uc), but people “my own age”[1] couldn’t see pictures of uncensored sex even though we could legally[1] perform those acts.
I’m now in Berlin, where “Dildo King” is advertised on rotating billboards in the City Centre next to adverts for kid’s dentists and nobody bats an eyelid.
In the other direction, I also remember being shocked when I first visited the USA and seeing “to my dad” and “to my daughter” Valentine’s Day cards in the supermarket.
[1] My own age at the time being the age of consent in the UK: 16
