Overview
"睡姦" (suikan) refers to a term in Japanese that describes a specific, non-consensual sexual act involving someone who is asleep or unconscious. It's a form of sexual violation and is considered very illegal and immoral.
"Somnophilia" is a fetish in which an individual experiences sexual arousal from engaging in sexual activity with someone who is asleep or unconscious and can vary in its expression. In its consensual form, partners might engage in role-playing or other activities where consent is given in advance. However, non-consensual somnophilia, where someone acts on these desires without the other person's consent, is a form of sexual assault and is illegal in most jurisdictions.
