As with many things in the D/s or more so M/s relationship, it is the 'taking of the mind' that is important. The mind and imagination the biggest sex organ.

I find with my subs and slaves that humiliation is part of that 'mindfuck'. It allows them to move from out of the realm of vanilla responsibilities and pressures to the realm where it doesnt matter WHAT I call them, they are 'given over' to Me and My desire and lust. It is very often the 'switch' needed to take that step into paradise where they truly ARE my slut/whore/cunt/cock.

We both know that I treasure their submission and she/he know that I will respect their hard limits.
It is discussed between play times. But during play, their mind body and even name, belong to ME.
Humiliation is a tool I use to draw them from vanilla into my world.
An effective tool in establishing submission.

I have only mentioned verbal humiliation. Bu there are many other ways of doing it.

Remember, there is no right or wrong way. If humiliation doesnt arouse you, I'm sure you can find something else that will work. :P
