I agree with aspects of this. I adore humiliation in both my sub and Dom life. When I'm being vanilla I often have to force myself to start thinking of things as humiliating to be stimulated. Something as mundane as missionary sex turns into an elaborate game of humiliation so that i can reach orgasm. So I can related to being able to see things as humiliating.

Flamming RedHead has a very valid point that we must stand back and look at what our parents would think. Though i think that also points out how relative these feelings are. Humiliation is cast upon us by social pressures and norms. If we lived in a Gorean society would it be as humiliating to be a cum dumpster? If that's something our mothers were called would it be such a turn on to be called it or just common place?

I simply think it is so relative that if you don't feel humiliated by the act then the act is not humiliating.
