My T say's the standard list of acceptable and expected things to talk about in therapy is:
The past,
The present,
"Us" as in therapist client relationship
And sex.

Websites are for new clients, there was likely some problem with the responses she was getting. You are an existing client. I encourage you to talk to her. Ask about the book and removal of that part of the list. That conversation may help get you to the conversation you've been wanting to have.
