This was another interesting thread that had focused on humiliation, by TDS, I was hoping that more people would have responded to it, as I thought it was very interesting and hopefully TDS will be back soon to revive the thread and give his two cents on it.

I consider myself to be an exhibitionist, and I think that humliation just came naturally to me.
It is interesting that the more you start to enjoy it the more you find that your limits can be pushed farther. Eventually what you used to find humiliating, is just another thing you do.
I play online with this every once and awhile, but I do have to watch, as humliation can be harmful it you don't play carefully, usually I tend to let my limits get pushed enough, so that the end result can be euphoric, but I end up getting a bad case of sub drop. I am usually left to deal with this on my own and it will sometimes last a week, before I am fully functional again.
Still I enjoy the humiliation aspect so much, I will always go back and do it again.
