I was tied down in that chair for 10 minutes and experienced what it was like to be completely powerless while someone else has complete dominance. It's sadistic, even though I find Richard to be a really lovely human being. That's what the whole film "Tickled" is about. It's not a film about tickling, but I think tickling offers a really good visual metaphor for the much bigger ideas that we were trying to get at about power and control - by people who have a lot of money - over people without money and who have no power in the relationship.
