Female led relationships discussion

Whether you are the Goddess, or the sissy/slave. I need advice because I am seriously considering giving up 24/7 control to one of my exes. We played some pretty kinky and extreme domme sub games for many years when we were together. I am near retirement (early, I am only 55) but we have been talking and I think i would accept being 24/7 sissy to her domme. My challenge is that iw ould like 24/7 365 chastity, and as frankly as I can say it, I want to be abused. I know that sounds like someone off on a fantasy tangent, but I assure you it isn’t. I want to be reconditioned and broken down and rebuilt into an absolute servile human being. My question to both side of this equation, is this realistic, I trust her absolutely and have no concerns on that level but is it realistic to live 24/7 as a servile passive sissy with no orgasms ever again, living in a constant state of desire and frustration while serving. In my mind I imagine a period of a month or so when we get tother that I would live in an empty room with a chain and collar like an animal, fed when she wants and going through daily conditioning exercises designed to mold me into what she wants. She is bi polar and that is part of what we split over but now, I look at that instability as a plus because I never know what her modd would bring and there could be times of serious neglect and abuse, and I can’t help it, that excites me. So is it realistic and possible and has anyone else ever done this, what was the outcome, do you still live like that now?
