Those that are new to the whole BDSM, S&M, D/s, T&D (pick an acronim, any acronim!) play can easily wander away from intimacy. I think it is essential that there are chill-out times, to discuss feelings. I also think that a lot of women will be surprised how many men still want to see a demonstration of affection, even at the receiving end of a crop or stap. (I'm obviously speaking from my personal experiences, here.)
Even edge play needs a 'come down to earth' afterwards. - A reafirmation of intimacy. It is important to remember that power exchange should bring lovers closer together.
