Rainbow - first of all, I am glad for the positive feelings you had with this. I am glad you "got what you wanted" and it made you feel good. It seems this is an issue that is just very important to you and your healing and perhaps your T has understood what is good for you and wants to help you in the way that she did. I have no doubt in my mind that she deeply cares about you.
I am not too concerned about the confusion you feel, this might be something helpful to work out with your therapist.
As the other poster said, it does sound a little concerning though that you seem to be at the receiving end of a therapist who obviously is training a lot (which is good of course) but she "tries" this out with you as soon as she comes back from her workshop and is convinced as you state that "touch is the best way to heal trauma".
So you tell her about how safe you felt last session when she held your hand. And now this goes into a very advanced form of touch from then to now in what seems a short time.
So no wonder you are confused, no wonder you question where this might lead and no wonder you are afraid she will change her mind in the future.
And that confusion is not a good one to be in.
I would say, please trust your instincts, be VERY honest with your therapist and verbalize the confusion and the fear.
Listen to what your body tells you about this (haha, now I sound like your therapist) and try to remember what it is that made you feel safe and strong.
Perhaps this really is exactly what you need.
BUT, take actively part in the process and don't let her just try out things on you. She needs to be very careful what this means to you and I hope very much she knows what she is doing for your sake.

All my love,
Amelia
