My T is older - almost exactly my father's age, actually - off by a couple of months.
He has expressed his own paternal countertransference, and we freely talk from these places a lot. Meaning he will express that his paternal & protective feelings are quite strong at times. (E.g., when I have shared about a trauma). Although in much warmer terms than what I just stated...I'm not sure I'm comfortable expressly sharing some of what he's said verbatim. I'm slightly embarrassed by what I find comforting, I guess.
