As long as you remember the safe word...err...motion, then you should be fine.
I'm not as big a fan of the life endangering kinks, but I do understand their appeal to others. Whiel I agree it is a form of complete submission, and even though most of the D's Ive been with I have trusted without a doubt, sometimes, people can be enjoying themselves too much and can take it to far, or something can go wrong. Hence why I stay away from the dangerous ones.
