If “They” Insist you do not need a Safeword.

While some prefer to play without a safeword, I will always speak against this practice. Safewords are crucial to a healthy D/s because without them, there is no way to revoke consent which means you or your partner may not want to continue, but have no way of communicating this.

If your partner insists that you not use a safeword, you need to be firm in saying that will not be the case. I would take extreme caution with playing with someone who has suggested this, as it shows a lack of responsibility for your or your partner’s safety and mental health. Safewords should always be required of everyone to play safely. If you don’t want to use them, don’t use them–but always have them in place.
