We all know what this is, right? A paraphilia, or sexual fetish that involves corpses. Like many sexual fetishes, necrophilia has the potential to reinforce common cultural inequities. The overwhelming majority of images and commentary online to do with necrophilia are rape fantasies, or jokes that imply rape. ("She can't say no if she's dead.")
(I could comment extensively here also on the Vampire Romance genre as a form of necrophilia, but properly speaking, necrophiles prefer the dead, not the undead or living dead.)
At the same time, stories about necrophilia can turn the tables on rape culture, or explore more sensitive territories (no play on words intended...well, maybe a little). Remember "Kissed"? The woman protagonist's necrophilia was based not only on her obsession with death and dead things, but on her ability to perceive exquisite beauty in the process of dying.
"Kissed" has a convoluted set of origins. The film is based on a short story by Canadian writer Barbara Gowdy. It appeared in her collection We So Seldom Look on Love. The title of the collection - and, presumably, the inspiration for the story - came from a mock ode poem by Frank O'Hara, "Ode on Necrophilia" (source).
