Demon Lover (1992)

Jenny Harris has a rather difficult time with the men in her life: her husband is an abusive clown who cheats on her, and her boss is a rude jerk. Her new neighbor Rebecca proposes that finding herself a fantasy lover is the way to solve her problems. A little séance later, and Jenny does in fact have her very own dream lover. Despite him being a beer-bellied guy with a creepy face, he seems rather irresistible and at first improves Jenny's mood quite a bit. What our heroine doesn't suspect is that her dream lover is in fact an incubus.
