Somnophilia (from Latin "somnus" = sleep and Greek φιλία, "-philia" = love) is a paraphilia in which sexual arousal or orgasm are intruded on a sleeping person by having sexual contact with them. Some signs or symptoms that may point to Somnophilia include recurring thoughts regarding unconscious or sleeping persons and feeling sexual urges when in contact with or in the proximity of said individuals. There are possible treatments of somnophilia such as hypnosis, behavioral therapy and 12 step programs designed to terminate the behavior. While treatment is available, a somnophiliac may not seek it unless the behavior becomes destructive, problematic, or becomes a legal issue, which it is the latter - no consent is given to sexual act in the majority of cases and falls under sexual crimes legislation (unless pre-agreed for instance with a sexual/partner).
