Some guys who are receiving whipping, caning or other punishment had a seemingly more intense reaction than some others. Some of them start crying or they start saying, "stop," and I can't take more, etc.

Of course, there are also lots of guys who do not get to that point or who have more self-control or a higher toleration of pain.

If you are a domme, what % of your subs starts crying during punishment or claiming he can't take any more and you are continuing? Or, does it never happen, cause, when he wants, he just safewords out and you stop the session or stop that activity?
