If I remember correctly, you've expressed having erotic transference for your T. From her perspective, it would probably feel inappropriate for her as a female T to accept flowers from a male client who has ET. The gesture would be read as erotic, and she would probably feel that accepting the flowers would encourage your transference.

While the situation isn't exactly the same, I'm a professor and I have to be careful about the kinds of gifts I accept from my students (and the meaning behind them). I've drawn my own boundaries which are to accept cards and baked goods, but not flowers or items of material value or anything that appears to be a "romantic" gesture.
