The most generally useful riding crops measure about two to 2½ feet long.
I ask, on a scale of one to ten, with ten the top, what is your overall feeling about the session? I then ask what was the best thing about the session, and on a scale of one to ten how good was it – and what was the worst thing and on a scale of one to ten how bad was it?
Caution: It’s not uncommon for the dominant to experience some feelings of depression and/or guilt after a session (a phenomenon known as “top drop”). Hitting another person, or otherwise “torturing” them, no matter how consensually it was done or how much the other person enjoyed it, is taboo. The dominant has just broken that taboo, and may be paying the emotional price for doing that. A good submissive, therefore, makes sure to thank the dominant for their time and attention, and reassures them (to the extent they truthfully can) that they liked what happened.
One retired professional dominant used to question her submissives by using the following formula: What was the best thing about the session? What was the worst thing about the session? What was the most memorable thing about the session? After her submissive had answered those questions, she would then answer them herself from her point of view. After these questions were answered, general discussion followed as appropriate.
