Hmmmm, my personal feeling is that this sort of discussion should take place with you as 'equals', not in a bdsm 'play' situation. They should be carefully considered descions, not ones taken because she has to jump one way or the other because she is being tortured to give an answer.
I can understand your frustration though. Why not just give her a time limit within which she must decide?
Am looking forward to seeing what others think.
