If you're "into the etiquette of bdsm" that's great. Just know, however, there are no hard and fast rules or even agreement on what is the etiquette of bdsm. Not every slave is going to follow the guidelines you found, nor is every master interested in having a slave follow them. There is no bdsm handbook or guide. If you're going to an event and they have rules, follow them. That's true for any social setting though, vanilla or kink.

For your own relationship, the only etiquette and rules that matter are the ones that work for you and your partner. They should be important to the two of you, not to anyone else.
