I see both sides to this.

1) If you went in saying you had sexual issues, I could see why he would address questions in that direction. When I revealed about my SI to my T, she had a line of questions which felt VERY uncomfortable, but she had to ask to get a feel for what was going on with me. It pissed me off and I felt terrible, but I realized that it became an issue when the SI came up.

2) Some T's use the first couple of sessions to basically fire questions at clients to get a feel for what they may have to deal with. I think that method sucks, but some have very little tact in getting "facts." (especially CBT therapists who don't rely as heavily on relationship transferances,etc)

3) Aren't complaints anonymous? Personally, I don't think you should have filed a complaint without talking with the T first. In this case, he may not have actually done anything wrong because you presented with "sexual issues." If you had talked with him a second time, you could probably have figured out if (1) he was wrong or (2) he was doing his job (in a tactless way).

4) I do hear your fear over his questions. Did any of his other behaviors seem inappropiate? Physical closeness to you, physical contact, other signs that maybe you picked up on.

I would go back with a list and make sure you address your concern. I would NOT tell him you filed a complaint. That is a MAJOR thing and no doubt he will terminate and take action to defend himself....which if he is a good T has already documented what he said to you in session.

You always have the right to leave, if you don't like his responses about why he asked those questions.
