Considered edge play because of it’s far-reaching psychological influence, you need certain controls in place before trying this kind of play. As with all BDSM play, establishing a safeword is essential. Discuss the scene thoroughly in advance, so the submissive can explain their boundaries. There may be specific words that really upset them or they might not want to be humiliated in front of others. Always keep these limits in mind. Aftercare is very important. Lots of reassurance in whatever form you enjoy (hugs, sweet treats, chatting, kisses etc) is needed to recover from the intense psychological play.
