Necrophilia

Owen Harper asked Martha Jones if flirting with him would still be considered necrophilia if he was conscious, after having been resurrected by the Resurrection Gauntlet and Duroc. (TV: Dead Man Walking)

Tommy Carmodie joked that Josh Randall participated in the hobby of "necrophiliac trainspotting" since he knew so much about cemeteries. Josh, however, claimed he'd worked in one. (PROSE: Psi-ence Fiction) Tomb raiders were potentially necrophilic. (PROSE: Grimm Reality)
