This is how I see it:

Regardless of what title you wish to use.

First you are free and curious and only really play at being a slave girl, eventually even submitting on occasion to the will of another or many as the whim may strike .

Then later on you start to actually feel as if it is right for you to be submissive and seek it out craving the feeling it gives and submit in more and more ways to a specific individuals will if you are lucky mabey even falling deeply in love and this is where most of us stop.

Rarely but it can happen,

if the strength of the bond between a Dominant and his submissive is great enough (strength of character etc not physical) and the, respect, trust and devotion is tempered by disipline and a love that know no bounds

....you start to submit to yourself as well as your Master, any conflict you struggled with about your submission dies and what you thought was love before becomes stronger anything eaither of you could ever imagine or describe.

It is then you learn what true joy lays in utter surrender.

It is then that you wake up a slave at the feet of your Owner.
