Native speakers differ on the meanings. Others have their own opinions. My interpretation is Shibari means binding; macramé, and Kinbaku combines this with sadomasochism (Seme 責め) and eroticism to become Kannōnawa. Baku is the word for restraint. Whatever term used, it’s just bondage using rope.
We all have interpretations of what constitutes sensual, erotic and carnal. Consent is fluid. I have to identify partner desires, goals, fears and taboos to determine requirements and limits via solid communication.
