Female led relationships discussion

A very intriguing thing has been brought to my attention by my Wife/Keyholder. While talking with each other about how this latest lock up is going, she pointed out that she sees changes in my behavior already. When I pressed for specifics, she simply smiled in a very seductive way and teasingly pointed out she wasn’t going to tell me. What I found intriguing is that it’s only been 2 weeks. I’ve gone as long as 90 days before and generally am not really aware of any changes in myself until about 6 weeks in. I have no reason to doubt that she sees something in my behavior and I am certain she will share her insights when it suits her. But… The whole incident brings to my mind two questions for the Keyholders out there: How quickly do you notice changes in the behavior of those you lock up? What kinds of behavior changes do you see occur earliest?
