I don't know if we can say that because YouTube censors some things that whatever it censors is counterculture. I guess pornography has been the ultra counterculture for a while now, or filming and streaming executions. But IDK, I don't consider just sexual material to be a culture. Maybe specific fetishes, like sexual enslavement fetishes?
Obviously not everything they censor is counterculture. But a lot of counterculture is censored.
Sexual acts are definitely culture. "Giving head" used to not be a part of mainstream culture and now it is. It is a part of our language, or media, and most people's private lives.
Separately, the word "kink" is better than fetish in this context. Kink means not mainstream. Fetish means primarily psychological rather than primarily physical. I think that all kinky non-fetish things are bound to inevitably enter mainstream culture, it's just slow because of censorship.
