The word "pet" in a number of variations has been familiar to me for as long as I've studied the Lifestyle. I'd wager to guess it applied to the subbie/kinky/bottom/whatever sorts long before even then. I'm your age, littlepet, to give you a time frame to work with there.

Denu, thanks for the thread - some interesting info in there to consider. After all, The Lifestyle is nothing if not about continuing to learn and expand one's frame of reference. It's funny how the more experienced you get, the more important you consider the continuing education.
