I never did. My experience was more like starfishing's. I was open about my feelings as they arose, but it was my T who explicitly brought it up after it had played out for a long time. My understanding is that this is common in psychoanalytically informed therapy: that the T brings the transference into explicit sharp focus only at the point the client is able to reflect upon it from a position of emotional strength, rather than act/express it through unmet needs. That's where the astuteness is especially important, I think. If it's brought out while the needs are still active, the realization that the T can't fully meet them can be too painful to bear. If timed correctly, there is a tinge of sadness or regret at the realization, but it's greatly tempered by the experiential awareness that the caring received is enough.
