Puritanism in Movie Chat?

So I created a thread about a certain liaison that I had posteriorly, and it was deleted by the moderators

I see lots of threads on all kinds of topics on here. Threads about violence, about sexual orientation, about gender, about sex workers, etc.

But when I describe sexual acts in a bit more detail then it becomes pornographic? It seems that if I were to take a conservative perspective on anything even remotely sexual that it would be deemed conversation-worthy. But sexual talk from any sort of sex-positive perspective results in censorship

To be clear, the thread described me receiving a sexual favor from another male. The whole thread was a joke, if I'm being totally honest, but it bothers me that I can't make vulgar gay jokes even though there are plenty of vulgar sexual comments on the pages of hot female celebs
