Yep, I do this sometimes, both because I express myself better in written form and because sometimes I'm afraid to say certain things out loud. So I'll type and print something out and hand it to him at start of session to read. Or I've held onto it and read select parts to him. I also recently sent an e-mail where I was like, "We really need to talk about x in session. I keep pushing it away, but we should address it." He said he often gets e-mails like that from clients, and it's fine to send something like that.
