While I think a therapist needs to be flexible enough to meet a client's needs, there are going to be some therapists who are simply uncomfortable with certain things. In those cases, I think it's the therapist's responsibility to tell the client that it is simply not something they are comfortable doing. At that point, the client can decide to accept that or to find someone that is more willing to meet that particular need.

As far as doing things to "win the patient's trust"...I'm not sure if I agree with that at all. I think the client and therapist need to build a relationship that contains mutual trust through an honest interaction. If a therapist is doing things they aren't comfortable doing or that they feel is not therapeutic or that they are going to stop doing once they have the client's trust, then that's not a basis of honesty and it could break the trust further down the road. Instead, I would expect both client and therapist to work towards building trust with each other by starting as they mean to continue. Each needs to be as honest as possible with the other (even if that means saying "I can't do that" - therapist or "I can't talk about that yet" - client). Each needs to be willing to talk about issues within the client/therapist relationship, and own their own stuff. I feel like trust is a two way street. It's impossible for a therapist to win the trust of a client who doesn't want to give their trust or doesn't want to also be trusted by the therapist.
