Requiem, as far as I know there are as many kinds of BDSM as there are people in it. It's mix and match, pick and choose, freedom to do your own thing.
I've never heard of the SM police checking up on what anybody did.
I use to hang out at the big clubs in NY and, Jesus, that was a smorgusbord. It was so hard to tell who was who and what was what that it was considered common couretsey to explain what you were if someone asked, just so everybody could keep track of each other.
Do what the hell you feel like as long as you're not draging (pre-scene, that is) your significant other into it kicking and screaming.
Good luck, enjoy, and let your imagination have a field day.
And a rollicking good time was had by all
