I think it is okay to ask therapists for something but they have the right to say no. I also think you can't expect a therapist to have training or experience in every issue. I have things that happened in my life that I know none of my therapists could relate to but I didn't demand that they get training. It would have been nice if they understood exactly how I was feeling but that isn't the real world. If I wanted someone to specialize in that area it would be my job to find one that does. The only thing I expect of my therapist is to show up on time and let me know when they can't, be attentive, offer support, feedback, and help if warranted, be professional, and be nonjudgmental.
