Being His Pet

I found my soul mate...after being in a very abusive and sexless marriage for 16 years, I met the man of my dreams. Also has become my Master. We dated for a while before he ever brought this up, the dom/sub subject, but i noticed when we would make love he loved to grab a hold of my neck and he would also spank me, which i love.
One day I was away on vacation and he called me and told me i was to receive a package in the mail and he wished that I would let him know as soon as I got it. I opened the nicely wrapped box to find a collar. Beautiful silver collar with a lovely heart lock on it. I was surprised to say the least. It not only was beautiful but it made me feel like "He truly loves me" this i know for I am to be his wife in 2 months.
We have shared many things about the submissive/dominating relationship and although I am somewhat new to it, I love it...the only thing that i wonder is how far do you go when you are the Pet of a dominating Master? I am reading the Sleeping Beauty Chronicles, and wow is all i can say about that..Do i want him to tie me up, spank me into submission, do i want him to make me kiss his feet at night...i don't know? Do I just give into his every whim make sure that he is pleased in every single way I know how to please him? Or do I just go with it and see what happens. I know for a fact that he would never make me do anything i don't want to or hurt me in any way. I guess I am just a little scared but turned on at the same time!
Okay so that is my story, not much to tell but when he gets back from being deployed, I am sure there will be more to tell..
