Aftercare is vital. Kink without romance- or at least a nice dose of both passion and compassion- is empty. If I wanted that, I'd go see a pro. Just kidding- I'm sure most pro's are very caring and compassionate towards their clients, my point is that without the affectionate and caring relationship, there is nothing to be worked on.
I'm sure those who know me would agree that even though I'm not "on" 100% of the time, those times when I'm not don't weaken me as a dom.
