Literally what it says

Tiana is plagued by an unusual problem, or as she would put it, "I don't feel any pain. It's the opposite, in fact... I feel pleasure... like I'm having sex without really having sex." Tiana is a young woman who has it all: good looks, her own apartment, a career, and a nice boyfriend. But none of that matters much to her when she becomes infatuated with her new mysterious co-worker. Suddenly, for no apparent reason, she starts to experience phantom orgasms. In front of her boss. In a taxicab as the driver is leering at her in the rear-view mirror. Anywhere, anytime. Tiana's life spirals out of control. Her relationship is on the rocks, people at work are giving her funny looks, an annoying friend from the past comes back to haunt her, doctors, therapists, and a priest are puzzled. No one seems to know how to help her as the orgasmic torture continues. Tiana becomes a detective in high heels, investigating - herself.
