Hello Thrall and All ~
What I Love about the pain is that it brings me to myself and who I am, and therefore to Whom I Submit, in a very open and unguarded way, and on a very deep level. It causes me to Feel nothing outside of Control and Submission, and to think of nothing else but the space I am in.
Answer to the next 2 questions is Yes, oh Yes.
The separation from the pain is just as intense for me, and depending what the separation is about, brings on a whole different set of emotions, also depending. If it is the ending of a session or scene, it takes a Time to level back out to day to day things again. If it is the ending of that Relationship with the One who has the Control, that is more painfull than any physical or emotional pain from a scene or session has ever brought to me. Though certainly in a different way.
On the last question; My experience is that > Once I had developed and Grown to Give my complete Submission to Another (and perhaps in part because I was allowed only One at that Time in this Style?), when that Relationship was ended it was one of the most excruciating things I have ever experienced in Life and Love.
I think once One has Grown to certain levels of this Style, be it Giving or Taking, when those Needs are unfullfilled, that that pain is just as great as the pleasure when those Needs were met.
Just my thoughts and experiences with these things.
