Switch
Someone who enjoys both tying and being tied and moves between the roles of rigger and rope bottom. The word is used across BDSM, not only in rope.
A switch enjoys both sides of the rope, sometimes as the rigger and sometimes as the rope bottom, without identifying with just one. Anatomie Studio uses the fuller form “rope switch”; Shibari Study’s glossary notes that the word is not limited to rope but covers many areas of BDSM and kink. The rigger Shakti Bliss describes switching as something people often grow into, starting on one side and later crossing over out of curiosity, because some spaces are short of people who tie, or to understand what rope does to their own body. Those she surveyed said that knowing both roles deepened their empathy and communication. Tying your own body is called self-tying. More in Both sides of the rope.
