BBW sub, I think I'm one of the more vanilla people on this site, so I can't always relate to people in serious power-exchange relationships. But I can tell you that in most of them, there is a sphere outside the power exchange, where you agree to the power exchange and the specific terms of it. In that sphere, you are equals. He doesn't set all the rules. You two set the rules together, and then say "go," and within those rules, he is your Master. The idea is that this relationship should be fulfilling for both of you, including rules about how often you meet, whether or not you have sex, and what his obligation is to you if he can't hold up his end.

Let me share my personal experience with this. I got involved with a Dom online who I was *crazy* about. Everything was perfect when we started talking. He set a rule for me that I was to email him every day, no matter what. I did this, even when he stopped responding (even via email!) for weeks at a time! I didn't know if he was busy, if he was testing me, if he had met someone else... But I didn't feel like it was my place to question him, because I was the sub. I really wish I'd had the strength to say "time out!" and share my needs. Instead, I kept at it for two months before he had the guts to just break it off and let me find something better for me. I spent a lot of time miserable and lonely and confused, and I wish I hadn't.

Good luck tonight. I hope you two can come up with some ground rules that work for both of you. There is nothing more fulfilling than giving up control in a relationship where you feel truly safe and secure!
