I believe your therapist would say no. IMO it would be an ethical violation on their part to see you naked. It's a cultural thing-at least in my culture it is not appropriate for me to be with naked adults while at work. In fact, I would probably get in trouble if I went to nudist camps and got "outed".

But it would make for interesting conversation with your t if you talked about wanting to be naked there. Who knows what you would discover?
