Don't get me wrong but why, anal rape is normalized in prison and army and normal straight couples almost always find it normal (in slavic circles of course). Jokes/threats about asswhooping and shoving objects up the ass (said to children of course) are normalized too.
It's true though.
It is an open secret that Slavs have internalized gay rape as a part of their culture for some reason, as a way of humiliation more than anything. Think of the rules of American prisons (ej. Don't drop the soap) but apply it to the whole region of eastern Europe.
