Planned to read it but only skimmed through it so far, but am not surprised to hear about the negative T feelings. I have read other materials that discuss how uncomfortable it can be for the T. Back then, I told my T I worried my ET feelings led to discomfort for him, scared him away, or led to feelings of dreading seeing me. Of course, he never disclosed that but I sensed it at times.

I've been the 'object' of unrequited love (and sometimes obsessions) many times, and while not as a T, I did not enjoy the ongoing focus, and it made me very uncomfortable at times.

There are several facets of ET, and I've experienced several. From what I read so far, the Ts were ok with some aspects of it but more uncomfortable with the more intense type. Xynesthesia, I think when you talk about working through, you are referring to the more intense kinds? Unrelenting unrequited love or a client trying to overtly seduce. I can see why those would stir up negative feelings.
