Vincilagnia is the scientific name for a paraphilic sexual arousal triggered by being bound or tied up. This arousal usually occurs during the bondage activities associated with BDSM-style role playing scenes.
The term vincilagnia comes from the Latin vincio, which means to bind or shackle with chains, and lagneia, which translates to lust.
Kinkly explains Vincilagnia
People who experience vincilagnia become aroused by being tied up or participating in bondage games. They may also spend an excessive amount of time thinking about being tied up or have recurring fantasies about this activity. While this paraphilia centers around the sensation of being tied up, people who experience vincilagnia may also enjoy being disciplined (whipped, spanked, etc.) by the person who binds them.
Vincilagnia is quite a common fetish and can easily be managed as part of a healthy relationship. However, treatment may be sought if vincilagnia begins to interfere with a person’s daily life.
