Alan,
Beginning therapy for CSA can be a troubling experience at first, largely because of the survivor's trust issues. I would say first and foremost bear in mind that the T is there to help you. If you feel that you are being led down a road that is not useful to you, or if you feel uncomfortable in any way, you should just say so. There are many approaches to therapy and you may be with the wrong therapist.
On the other hand, do expect that things will move very slowly at first and that you will feel very awkward and perhaps frightened. The T will probably not even get into real abuse issues at first. He/she will want to just talk with you, allow time for the both of you to connect, and built up your ability to trust.
The T's job will not be to solve your problems; you are the only one that can do that, and the work that has to be done has to be done by the survivor. The T's job is to help us along and get us through the minefield with as little further new pain and trauma as possible. The T is like a guide pointing us in useful directions.
Let me give you an example from a recent session that I had. She asked me what Little Larry's biggest issues are at the moment, and one I identified is his fear that maybe everything that happened to him really does prove how worthless he is - regardless of what Big Larry says. So my T said let's talk about that. We did, and after a few minutes she asked me, how old was Little Larry when he was first hurt. 11, I replied. So he was a child, right? Yes, sure, a child. Then she asked me, Larry, can you imagine such a thing as a worthless child? Then we discussed ways to make Little Larry see that. As you can see, she didn't "tell" me, she "guided" me and I had to take the steps myself.
That's the great thing about therapy. We make progress and it's OUR victory. We really can do it!
Much love,
Larry
