I recently came across a book called "The Love Cure: Therapy Erotic and sexual". I'm not very far into the book because it's a heavy read for me. In the very beginning (and as I understand it), the author goes on to explain how the word erotic has basis from the god Eros and in general referred to all forms of love. That over time it has gotten a more narrow and sexualized association.

It might be useful, if you have not already done so, to ask for clarification as to what your T specifically means by erotic transference, in relationship to love, longing, wanting, missing, sexual activity/behaviors, desires... and so on. Even though I associate my transference with my T to be parental, I have wondered about my longing and desiring feelings towards her and where it fits in terms of how I may feel towards a sexual partner/lover.
