I think what a sub has as limits changes as we grow and learn more about ourselves. So constant communication and dialogue is essential. I have some hard limits that I know I will never want to explore, but I also have an interest in exploring a couple of things that I would have considered were hard limits,two years ago, even a year ago. Ad of course if an agreement to push any limit was made than I hope it would only be after a good period of time when a D/s couple know each other very well and the trust is implicit.

I would expect a Dom/me would respect a sub's hard limit, even if it wasn't his/hers, or the relationship would no longer be safe, sane and consensual, it'd be abusive.

LOL probably stating the bleeding obvious....
