BDSM
Before people engage in BDSM, they usually talk about each of the partner's wishes and fears. They also talk about the things that they are going to do, and the order in which they are done. Such detailed conversations are common. As people get to know each other better, these conversations become more informal. In addition, participants usually agree on a safe word; with this safe word, the action has to stop immediately. Safe words are used to make sure BDSM is safe. Sometimes one person thinks the play is OK, but the other person does not. The person who does not think the play is OK will use a safe word or gesture. This means that the play must stop so nobody gets hurt or injured.
