The other two sums it up pretty well.

Id like to add affection. For me i feal that my gf love is shown in a wery real and unquistionable. Its really more intensive than just saying "i love you". But many more fealings are in it all than that. There is also the bonus of an interesting sex life, better communication (forced through the need for honesty), you get closer to the person as they throw away the masks which also increases the confidence in the relationship (no surprise can be bigger than this ), self confidence (your being yourself and no one is laughing, running away etc). There is just so many positive things in it, that it is hard to list them all even at the everyday there is positive feedback from d/s, when i look in my gf eyes, i can allmost see all of our shared secrets rolling in the back of my mind, it simply brings us closer together! Also when interacting with others our knowleadge of each other aids us. Im sure that we appear as "one unity" to others when they meet us i think i could go on rambling of all the good things my gf has brought me.... finally one might say its ok to be the freak i am
