My T doesn't tell me anything personal. I don't want to know. I especially don't want to know if he has children, as I think I would feel horribly jealous.

But he does talk about his own experiences in therapy if it's helpful to me, e.g. I said he seems to look much older in some sessions, depending on how old or young I feel in therapy that day, and he told me that, when he started personal therapy, he thought his T was much older than they were. That kind of disclosure is helpful to me.
