Well,

Weighing in on the discourse here....

My T discloses and that's what makes it a two-way street, it makes the relationship real. He has told me personal vignettes from his life that he thinks will match a feeling I'm trying to express. It's not all the time and its not everything, but I appreciate it when he does because it means he is really trying to meet me where I am. It makes the experience so personal. I don't know if I would last too long with a T who didn't disclose at all.

And, in the for what it's worth category, T has encouraged me to express my longings and desires and has reminded me that he has strong boundaries so I can feel safe.

I do not believe that there would be any crossing of professional boundaries in our relationship ever.
