I agree the consensus on the thread. Interests, limitations, ect., should be discussed prior to booking a session. There is nothing wrong with pre-booking inquiries so you can book a session with the lady you feel is the best fit. When I was an active session dom, I'd be uncomfortable about being blind sighted with a list at time of session. It is better to allow the Dom time to get her head wrapped around your interests beforehand and, also, time to decline the session if she feels it isn't a good fit.
