Safewords are essential tools for navigating intense, vulnerable, or risky play. They allow someone to stop or pause a scene immediately—without judgment or explanation. While common in kink, they’re useful in any context involving trust and physical/emotional intensity. The most well-known system uses traffic light colors: Red (stop), Yellow (slow down/check-in), and Green (all good). Everyone should know and respect the safeword(s) before beginning any scene.
