"More beneficial and valuable than I could of hoped for."

Truly, it was more beneficial and valuable than I could have hoped for.  You are extremely easy to converse with and a keen listener.

You know, I have searched over the last year or two for a "kink-aware" therapist that I could see but have never found anyone I felt comfortable with.  I realize that I was seeking someone exactly like You.
I thank You for giving me permission to focus on my needs.

As a subsmissive, I find that difficult to do at times.  But You made me realize that I must focus on my needs in order to truly serve, in that my needs are met by being in service and subservient.
So I sincerely thank You.  I hope that our conversation was enjoyable for You as well and that You found my comportment acceptable.  I shall send You a separate email with some suggested dates next week for a follow-up call.

Again, my appreciation.  More than ever, I am at Your service.

In devotion
