When my T asks this, I always try to at least think about what I need. Sometimes I just don't know. Sometimes I need reassurance or an answer to a question. Sometimes I need to know if I can call her during/after a stressful thing. Sometimes I need a note to put in my pocket or a temporary loan of something from her basket of little things she will give or loan to clients (transitional objects). Sometimes I ask what she can give me, although she usually dodges the question. It's still hard to ask though, even when I know she is willing to do certain things.
