Only yes means yes, everything else is a rape. That applies to BDSM too. By communicating boundaries, safe words, and preferences we lay the foundation for safe play. So when that scene starts it will always start with a yes by agreeing to the terms set up beforehand. Consenting to play, and an understanding that consent can be revoked at any point and the play stops. So, it’s why we come back to only yes means yes, everything else is a rape. If you ignore safe words, if you ignore when consent is revoked. Then that’s rape, full stop. If that concept is hard for you to understand, then you’re part of the problem.
