If you allow me Finding_Fantasy, I have a little suggestion for you. It may seem too little, or not physical enough for the true 24/7 lifestyle that you are trying to achieve, but it works for me.

Use your mind. Anything you do, everywhere you go, as vanilla as it may seem, do it for him, in the privacy of your mind. I'll give you a few examples but remember, this is me. It may work differently for you:

Early morning, I wake up. I make breakfast not for my boyfriend but for my OWNER. I do not need to serve him on my knees, I just have to remind myself that I am SERVING him. I wear sexy lingerie under my office attire not just to feel sexy myself but because I want to be sexy for HIM.
At work (I am a teacher) I am patient with the kids not just because I love them I they deserve it but because it makes me patient for HIM. I go to the gym not just to feel healthy but to look my best for him, because my body is HIS. I put up with the random human stupidity of every day life because I want to be able to endure ANYTHING for HIM. Every day I study and learn a bit of everything because HE likes owning a smart girl.

It all sounds very vanilla. Somebody else may just call it love. but for me that is what bdsm is, just a different kind of love. I love F. so everything I do everyday is bdsm and it is for him.

Very psychological stuff I know. But it works. And every day when we come home whether we play or not; if we have sex or not; or if he calls me Lady, sweetie, honey, slut or slave, I know I am being true to my chosen lifestyle.
