Safe call

Before going to play in a new partner's private dungeon for the first time, it can be useful to arrange a safe call with a trusted friend or colleague. This is where you let them know what is planned, with whom, where you'll be, and arrange to telephone them when the festivities with your new partner should have finished. It puts your new partner on notice that should you not call then they can expect the police to come knocking on their door very soon thereafter.
