Heavy degradation varies from person to person. One thing I see as a constant is that it is a stripping way of all ego. It is a purging of built up deep emotion and suppressed feelings. I was wondering how people can do that in a hug and goodbye pro session. Unless you've witnessed a heavy scene like that it is hard to imagine. I'm probably not describing it well.

Kneeling, crawling, boot licking and everything you mentioned is hot. I love it all and on either side, depending on the partner. I agree that what you describe is about control and power play. I see that as fun where as actual degradation is a different plane.
