Very important. Anyone who says that he/she is too “hardcore” for a safe word is the kind of person all subs/pets/slaves should watch out for. Even loving, caring, committed D/s couples (or couples participating in BDSM activities) have safe words. It should be a word that you don’t blurt out by accident or something that could be misinterpreted as part of a scene or roleplaying activity.
