Certainly every sub's/slave's aftercare needs will differ, just as it differs from Dom/Domme/Master/Mistress. There are indeed genuinely sub/slaves who want the additional excitement (even following subspace) to be "disregarded." For one thing it adds to the "being used" feeling. Aftercare which consists of anything from simple cuddling to full-blown spa visits can also depend on the intensity of the play and/or the maintenance of the sub's/slave's well-being. Like most things, there can be no general rules -- however, if the communication and empathy are strong between partners they will be sensitive to what to do when and why. Intense scenes are cathartic, even in some cases, metamorphic...passion changes the inner core, or at least it can.
