I have always heard that consistency is one of the most important characteristics for Dominants to have. It lets the ones who serve us come to learn what to expect. Mind you, the consistency is peculiar in that you can be consistently chaotic. Little bits of randomness thrown in, so long as you always do this. They come to expect it and miss it when it doesn’t happen.
But I have found that consistency needs to come from the submissives/slaves as well. From a personal perspective, I need my girl to behave in a consistent manner so I can determine when something is bothering her. Where I can know when something is up. When she is consistent, then this gives me the benefits of knowing what to expect. Giving me a basis for making good decisions on our relationship. When consistency is lacking, then I am often at a loss for what to do.
What are your feelings on consistency? What role does it play in your relationship? I am dieing to find out.

Hrmmm, well, according to the “what weather are you” on my MySpace. . . I’m lightning, and capable of random violence. Which is true. . . but apparently I’m consistent enough- from what I hear it’s easy to tell when something is bothering me, when I’m unhappy, and believe me, I’ll let you know when I’m downright pissed. But yes, consistency is good for just the reason you stated above. But dear lord, don’t let ANYONE confuse that with being boring. random is good, surprises are good, but only if you know your partner well enough (ie- what kind of things would be surprising and random in a GOOD way, and not a BAD way – make sense?) No one likes to see the fake “gee, you SHOULDN’T have” face 😉
