Yes, the first time I think I just said, "I brought something that I would like you to read. Is that okay?" My former T wanted me to read it aloud to her, but after I balked and gave her a hard no, she read it silently to herself. With my current T, I have found it useful to write about things that are difficult to talk about or things that I feel outside of session but not when I'm with her. I think it's a pretty common thing to do.
