Currently facefuck, face_fuck, and facefucking (but not face_fucking for some reason) are all aliased to forced_oral. To me this is incorrect. Face fucking involves hip thrusting, some sort of motion by the male, meanwhile there are many images that I would say depict forced_oral, for instance a character holding another character's head preventing them from backing up, that don't include actual face fucking.
A better tag for this family of face fucking tags to be aliased to would be irrumatio because it literally is the technical word for face fucking...the definition being: "a form of oral sex where a man thrusts his penis into someone else's mouth." It couldn't be a more perfect match.
So this conflation of face fucking/irrumatio and forced oral is just incorrect imo. Neither should be aliased to the other, because at the end of the day there are plenty of cases where one is happening without the other.
