If this question has been asked before, forgive me.
Spankees, do you find that your pain tolerance changes throughout the month (if you're female, obviously)?
If you are spanked on a regular basis, has your pain tolerance gone up over time? Does it depend on the warm up, or time lapsed between spankings?
If your tolerance has indeed gone up as you've been spanked more regularly, what have you found (if anything) that you can do that can break through that 'toughness' you've developed?
