I agree, there is no TMI in therapy. My T and I have definitely had discussions about sexual topics and she has always handled them in an appropriate and professional manner. Usually, I am the one who brings them up and my T follows my lead. However, I would be comfortable if she brought them up, too, given she had a reason to do so. For me, there isn't anything T could ask me that I would consider off limits. That's partly because I'm an open person and I feel comfortable talking about sexuality, and partly because of how much I trust my T. I know that if she asked me a question about sexuality, it would be for a legitimate reason. So, while my T has not asked me that specific question, she has asked me other questions that are just as personal. And, if she did happen to ask me that question, I would have no problem answering it. But again, it all depends on the context, the client's level of comfort, and the relationship between T and client.
