Slave and master

A tenuous and empowering relationship.  How do you work that desire into a profile on a dating website?  Single female, enjoys cooking, rock climbing, reading, sci-fi movies, shooting pool with friends at a local pub, camping, hiking, and being tied up and whipped into submission.  Looking for a woman with similar interests who is or can grow into being a good master.  This dynamic was painfully missing from my last two relationships, which leads me to believe that being a good master is harder than I thought.  I did a stint years ago as a dominatrix and I didn't think it was that hard.  Although, I had no emotional attachment to any of my clients, only their wallets.  It does take an intense emotional bond for the Slave/master dynamic to work.  So, not only tasked with finding that someone special in life, how do I find a girl with that extra special quality?  I'm sure there are websites that cater specifically to the wants of women like me, but my faith in internet dating is definitely waning.  I do know that being honest up front with someone about your desires is best, but not really first date material.  When is the appropriate time to bring this up to a prospective mate?  Second date, third or fourth?  After the first time you have sex or before?  Or maybe during the first time you are having sex.  What is the etiquette for bringing up bondage?   Too many questions.  Where is that book of answers that I bought last week...oh, that's right, the book store was out of them.  Until next time.
