Content warnings for the epilogues?

Hello! I finished homestuck about a day ago, and I heard that the epilogues were quite vulgar when it comes to the content. Multiple people have said that I should probably wait until I’m older to read it since I’m a younger reader.

Could anyone back this up? I trust y’all but I wanted to just get a clearing of what it talks about. Homestuck didn’t rely on very crude humor to be funny all the time so I’d like to know what’s different.

Thanks! :)
