"just some girl" posted that there has to be a boundary in therapy, that some thing are TMI. I asked my T more than once if anything is TMI in my therapy. She said, emphatically, "no". So, I've told her some very embarrassing stuff about sex and it's always been okay with her.

She asked me questions about sex early in therapy but nothing about "touching myself". I wouldn't have liked the question. It's different when a client brings it up vs the T.
