Indeed, what counts as safe and not-safe varies wildly by culture.
I live in Berlin, and outside my apartment there is a spinning cube of adverts; the face of that cube advertising for Dildo King is between the face advertising for family cargo bikes and the face advertising for Edeka (a supermarket). There are also several nudist beaches within the city limits.
From outside the USA, I sometimes hear things such as Florida wanting to treat cross-dressing as inherently sexualised and therefore criminal if done in the presence of minors. (Was that a true story? When I search for it, I get transgender issues, rather than cross-dressing, so I can't find out if Hillary Clinton's trousers are a literal fashion crime in Florida).
