I remember seeing this news story about 2000 year old chinese tomb that had bronze dildos, strap-ons and buttplugs in it, and just how akward the state-sponsored professor was talking about their use. Because it was a man's tomb.

He went full "oh, they were just probably meant to hold in the chi, which was very important" and beating around the bush, clearly embarrassed. As if he had been told by the state to downplay it like this wasn't totally flaming gay man's ancient tomb, because ...you are not supposed to say things like that in China.

Much like all authoritarian governments, they have issues accepting that some people, maybe even their ancient ancestors, might be into gay stuff. Because that's not "manly".
