I’m Japanese and currently studying abroad in the US. Recently I was telling some classmates about onsens and how my family are enthusiasts and they were so weirded out by the concept especially when I told them that my father & brother go together the most (people are fully naked in onsens if you’re unaware). Non-sexual nudity was never a big deal to me and in Japan where bathtubs are the norm instead of showers it’s not even unusual for same-sex family members to bathe together (one at each end). Where does this prudishness come from? Especially in a country that’s known worldwide for its hyper sexuality (Hollywood, celebs, porn industry, etc.)?
That’s actually normal in sexually repressed societies.
Similar stuff happens in Iran, where young people get down to crazy freaky sex because they’re so sheltered from it in everyday life.
The more people are told “no,” but the only reasons are religious reasons, the more will rebel against it.
So while it seems backward, the US is hyper-sexual because of it’s prudish history. This was a country colonized by people who thought dancing was a sin.
