Effective communication is the foundation of safe and consensual BDSM practices. The Traffic Light system is a globally recognized method for establishing boundaries: 'Green' signifies that the scene is going well and both partners are comfortable, 'Yellow' indicates a need to slow down or check-in, and 'Red' means stop immediately. Implementing these clear verbal or non-verbal signals helps maintain a safe environment for exploration while ensuring all participants remain within their agreed-upon limits.
