The most common cause of sexsomnia is Ambien or other sleeping pills, reports Glamour.

“A sleepwalking person or an unconscious person or a person with dementia or Alzheimer’s or a person with sexsomnia cannot give consent, even if the partner were to ask,” says couples and sex therapist Stephen Duclos, LMFT. “If the partner were to ask, and no conversation was possible, this might be an indication that something was wrong.” Usually, once the sexsomnia sufferer’s partner realizes their partner has been sleeping during sex, they stop doing it to avoid any violation of boundaries.
