Just as Miraculix I have no experience of on-line relationships. But off-line it depends on the slave. For her it's what ever symbol my slave thinks represents submission the most we get. So far it's all been dog collars. But different types. When it's on then it's official. And for me it's the names. That I call her "slave" and she calls me "Master". Nothing big with low cost but with a profound importance to me and marking the step to the new level.

I'd never let some one-night-stand or some girl I'm banging call me "Master". For me, that word carries a lot with it.
