Negotiations of where once boundaries are and using a safe word, is useful tools chemsex-participants can learn from BDSM communities. Submissive masochists can enjoy being inflicted pain upon, and crying can be a form om emotional release that is sought after. "No" can therefore be a part of the sexual play.
A safe word is when you, before you start playing, decide on a word that all participants agree on is the sign to "stop". This way you avoid confusions. The word chosen can be far from a sexual word and that completely breaks with the sexual vibe in the room. Chemfriendly have been talking to chemsex-participants who have engaged in BDSM-sex without using a safe word. And although this
can work out all right, we have been told that the dominant can leave the situation with a sense of doubt that can be hard on their mental health. Not to mention that as the dominant you may end up actually violating someone boundaries because you were not able to distinguish between a "no" meant as a part of a roleplay, and an actual "no".
- Use Safe words. Unless the submissive part says, that "no means no".
