Not a good dominant ... a dominant does ask for the Sum'tastes ...
Sort of a myth Messa. Those things should be decided well before any play gets started and a safe word should be established.
If as a submissive you are trying to control things during play then you are doing what is called in dancing 'back leading' and inevitably that ruins the play as it does the dance.
So all a sub needs to know going into the play is the edges of the envelope and how to bring things to a halt if necessary.
Otherwise you are just "playing" submissive and you really aren't one. Besides isn't the purpose of playing and exploring to find out new things.
Some people might say we are engaged in semantics but believe there is a significant difference. It's like a "dominant" asking permission to do something during play. If you have to ask you either have no clue as to how to be a dominant or you really aren't one.
Sort of like "50 Shades of Gray" isn't, in many ways, a true BDSM relationship.
So to circle around back to the start if I agree that a Dominant can rope me to a cross, if I am a true submissive, I shouldn't be saying 'You have to do it this way'. My part in the decision making process ends with "Ok, let's do it."
