The term forniphilia was coined by bondage artist Jeff Gord who specialized in the subgenre and maintained the website "House of Gord" on the subject. Forniphilia as a form of bondage usually involves the subject being tightly bound and expected to stay immobile for a prolonged period. Subjects may be gagged – a forniphilic gag is a type of gag that has the primary purpose of sexual objectification or erotic humiliation. Subjects may also be placed in a position where there is a danger of being smothered. In many of Jeff Gord's human furniture creations, vibratorswere also used. Proper safety requires frequent checks of the submissive's well-being.
