Sexsomnia aka Sleep Sex is a parasomnia (sleep disorder) that causes a person to engage in sexual relations while asleep with no memory of the event.
Sexsomniac: I woke this morning feeling tired and found used condoms in my house. How is this possible, I do not recall having sex and I was alone last night when I went to sleep?
Doctor: Sounds like you may have Sexsomnia. Let's get you into a sleep clinic for further review.
