Gynophagia is the fetish of a person becomming food for someone else as a fantasy. as a fantasy it's just as taboo as BDSM or other kinks (I won't list everything here). actually Gynophagia can really be a more gentle fetish than BDSM because torture is almost never applied. honestly when you boil it down to its essentials (no pun intended) Gynophagia is an extension of the damsal in distress scinario like you see in stories and such.
Gynophagia is present in alot of the older media we have, the most widely recognized being a helpless woman being boiled alive by a native tribe when the hero rescues her.
another example would be in Little Red Riding Hood where the wolf devours Red Riding Hood, but this could also be classified as a seperate but similar fetish called Voreaphillia.
one of the more widely known scenarios of Gynophagia is known as the Dolcett method which usually centers around the main female character of a Dolcett comic being spit roasted alive and enjoying every moment of it.
but again I must stress that Gynophagia is one of those few fetishes that can only be a fantasy and should not be practiced in RL (Real Life).
