The Hunger (1983)
A hallmark of Goth culture, "The Hunger" is positively drenched in sex, from the opening erotic kill scene which sees vampire Miriam Blaylock (Catherine Deneuve) and her lover John (David Bowie) feasting on two club goers to the seduction scene later on between Miriam and Sarah Roberts (Susan Sarandon), the doctor intrigued by John's sudden aging. The sexual tension between the women grows throughout the film, and Sarah even asks Miriam, "Are you making a pass at me, Mrs. Blaylock?" The resolution comes shortly after the moment when Sarah accidentally spills red wine on her white top and feels obliged to remove it... her top, that is.
