There is actually this whole group of therapists who generally seem to be very out of fashion for some reason but who are actually trained in these things and who have experienced transferences themselves. These are psychoanalysts who are required as part of their training to go through their own personal analysis at least four years with several hours per week. This time is enough to experience all sorts of feelings towards one's T. I'm pretty sure that in addition to that, they have extensive theoretical training in that too. So it is not that all T's training is lacking in these terms.
