Do you not have regular conversations about what each of you likes? Surely that's important no?
If it's left entirely to the KH to make up what happens, that puts an awful lot of responsibility on them doesnt it? What if they dont really want all that responsibility all the time?
There is nothing wrong with communicating with your KH as to what turns you on, or what your current needs are. They're probably not mind readers, but they probably do want to please you. Unless you are going out with a complete bitch, then she will still want to please you. Relationships are just like that, that's the way it is.
I ticked yes, because it's not only ok for a sub to say what they'd like to happen in a session, it's more or less imperative that they do. If the KH then chooses to grant the sub the pleasure of making those things happen then that is upto the KH. I probably don't have to point out that I'm not suggesting for a minute the sub should be constantly saying "Now do this...."
Communicate. We keep coming back to this. Without communication, none of this works.
Stop playing the way you think it "should" be done, and do what works for you. And be open and honest in your communication.
