O-ring

The O-ring is a symbol from the BDSM scene that traces back to “Story of O.” It is usually a ring with a small loop or additional element that references the novel’s well-known symbolism. Some people wear it as a discreet sign of belonging to the scene, and it may have different meanings, such as a submissive or dominant stance or a general interest in BDSM.

Its exact meaning is not standardized and can vary by region or from person to person. For that reason, one should not infer a specific role from the ring alone. Claims about wearing it on the left or right hand are not universally binding; if the ring is used as an identifier, context matters. It is also important that the jewelry fits comfortably, is safely made, and does not interfere with everyday life.
