I totally mirror what Jones and Caroola have stated. I did become intimately involved with my first male therapist. Became involved with his life and his family and later on down the road an affair. It seemed like I was swept away by it at first, but one day 6 months into our affair ExT decided that he could no longer continue because he felt "guilty" for cheating on his dead wife, and I wound up trying to kill myself.
I don't think it is ever ever a good thing to become involved with a T outside of therapy and especially in an intimate sense. It is always damaging to client in some way.
It is ok to experience sexual feelings and fantasies about our Ts, but talking through it... is the only way through it.
I hope that the T you are with maintains appropriate boundaries. Perhaps speaking with a male T would better assist you with the ET feelings and then you can resume back with your female T?
Best of luck to you.
