I believe that a visit to lady such as your self is a way of being in a situation that the visitor no longer controls.
The chastity thing is an extension of the helpless feeling.

For me I was frustrated that I was never really out of control.
This is compounded by a high pain threshold so I never really got what I wanted.

The thread on the Girlfriend - Domina relationship brought wonderful fantasies. That is chastity and impact play.
