For me, the definition of submission has evolved over the last 6 months. Master and i went from bondage play and s/m play in the bedroom to it becoming a lifestyle. The difference is that my heart was not in it in the beginning-just my naughty parts . But as our relationship grew, Master realized that it was in my best interest (and hers) to be Dominant/submissive with everything (generally) in our personal life. But for example, I don't ask to go to the bathroom unless we are scening but I do ask before making decisions that impact our lives. I was so independent before and longed for a way of becoming more myself by trusting someone else so completely. This is what submission is for me. I am free to be myself and serve Someone else so completely. It fills me with great satisfaction to meet my Master's needs completely. We are monogamous and she has promised to never trade or share me with another and I promised her to never serve another. I still struggle with submitting sometimes but Master is quick to recognize where the issue is coming from and addresses it right away. We live harmoniously and in balance because of the roles that are unique to us. I do believe however, that there are many forms of submission and what is right for one is not necessarily right for another. We are all unique and so is our submission, IMO.
