Oh I don't think it's a flaw. I know some psychoanalysts or whoever sometimes talk about a mandatory erotic transference but I don't think it must be part of every therapy - sometimes no love is felt - nor do I think it's necessarily transference when love is felt. It may be actual love. Due to ethical code they have, of course therapist can't act on it, the real or the transference kind, even if they do love the client in return.

I think once in a blue moon a client and therapist may happen to be near soul mates and love each other but not be able to do anything about it. Different time, difference circumstances...

I've had mostly female therapists and couple of them I felt nothing, and one I loved. It was during my teens so I think I was looking at her as a potential partner and it wasn't transference or anything. In other words, I felt an attraction to her as soon as I saw her. Of course, it did not help that she was understanding and caring (during our sessions of course). I wished she was mean sometimes, like Petra might say, lol.
