To my understanding, submission is a choise. i think it is a choise once, or at least not frequently, because there will probably be times where it may be boring, difficult and exhausting, but then one knows inside her that it would be a pity to let submission go because of the hard moments.

i am not sure that there is any special virtue in submission however a profound and unique joy may be found both internally and in the D/s relationship when the times of resistance are over.
