Merinthophilia is the condition of experiencing sexual arousal when bound, restrained, or tied up. For some the pleasure comes from the feeling of relinquishing control to a dominant partner. Others find the feelings of immobility and helplessness pleasurable on a tactile level.
Kinkly explains Merinthophilia
Merinthophilia can be explored in rope bondage where the tying up is the focus rather than simply the means by which to restrain a submissive partner. Rope bondage enthusiasts explore many elaborate and, in some cases, quite artful uses of rope for restraining and suspending their partners and this can give both paticipants great pleasure.
