I don't like the sound of that. Serious alarm bells are ringing in my mind that your T is encouraging you to perform sexual activities while on the phone to each other, regardless of the condition which I know from others is extremely difficult to live with. My concern is that your T is using your behaviour for her own gratification, under the guise of concern for you. Either way, it isn't ethical practice to be doing this. Her encouraging you to find ways to managing your condition and impulsions in your own time is another matter, but with her is a no no, sorry.
