I think your t should know how you felt after your session. T's are trained to deal with these emotions. Sharing your feelings may open the door for discussion. As for it being manipulative, that really depends on your motivation for sharing. If you want to try to make your t feel bad then, yes it might be manipulative. If you want your t to know how you felt after session so you can work through the feelings together then I would not see that as manipulative.

I can't speak for your t, but my t has told me she will not read from my journal. She says if she does I will alter how I write in my journal, which is the one place I am 100% open about my feelings. I know this is a boundary/rule for my t and I respect that. I know she has that rule to make sure that I have a safe place to let all my feelings out - especially feelings after a bad session.

However, I do take my journals to sessions and on occasion have shared from them. But I have to read it aloud. Sometimes I will take my journal and write out important points or feelings I want to share with t. It can be difficult to describe how you felt when a week or two has passed between sessions. But I've often found this has given me time to reflect on my feelings and be able to discuss them with t.
