Love Hurts.
While watching the season premiere of Fx's
Nip/Tuck, Sean and Christian, the two main characters, are asked to work on a television executive who opens his shirt to reveal, of all things, bite marks.
Sean innocently asks if he was attacked by a dog. The exec is quick to deny this, explaining that when his "Dark Mistress" puts on his collar and leash, he becomes the dog.
Coincidentally, the exec explains his reasoning for using the dominatrix as exactly the ones we discussed in class - relinquishing the power for a brief period of time.
It was interesting to hear a mainstream TV show explain this.
