Everyone has given good replies, but I can't help but want to add my two cents.

One thing I've had to come to terms with is that submission isn't always going to be a non-stop party. It's not always gonna be fun. CD isn't necessarily fun right then, but the orgasm after is (imho) fantastic. My Master has had me keep myself aroused without letting me cum for a couple weeks in the past and, while not a barrel of laughs, I eventually appreciate it 1. because I have the most intense orgasms after and 2. because it teaches me self-restraint since he hasn't always been on the phone to tell me to stop when I'm getting too close.

Submitting when you don't want to submit should (again my opinion) be what brings the ultimate satisfaction to you and your Dom. In domestic situations, you might not want to do those three loads of laundry or sweep and mop the floor, but you do it because it's what he wants and you desire to please him.

You mentioned that you couldn't help, but beg to be allowed release, even when he added days..... I encountered a phrase a while back that really helped me. "How can we expect another to control us if we can't first control ourselves." Sometimes, hon, we need to just bite our tongue and say "yes, Master" even if we don't necessarily agree. I've said just that to my Master. "Just so you're aware, on occasion when I say 'yes, Master' I may be submitting to you, but I don't always agree with you." And that's fine. It's not always going to be where you're both wanting the same things, but...that's when you understand that, because he is the Dom, his way goes.

Okay, this turned out much longer than I intended. *grins* I really hope this works out for you. Take comfort in the fact that he did heed your "safeword" even if somewhat misused.
