Consent is paramount in kink. If you're just getting started, or want to slowly introduce BDSM into an existing relationship, both you and your partner should make a list of your soft and hard limits. A soft limit is something that you're curious about yet unsure if it's right for you, such as name-calling. A hard limit is something that you are certain is off-limits, such as electrostimulation. Writing out your hard and soft limits with a partner is a wonderful way to get to know another side of each other. Along with implementing limits, it's important to choose a safeword that is not no or stop, because some couples use such language as a part of their role play. Your hard and soft limits will likely evolve the more you explore, so it's important to keep having these conversations with your partner.
