I quite like nothingtolivefor's take on this

Along this vein, is there any way you could sit so you weren't facing it? Some way of covering it while you're there? It seems like your T is just being plain awkward on this one.. any way to beat him at that game?
I feel for you, I know you've been struggling in your therapy/with your T because of something that happened and keeps coming back around, I'm guessing this is something that reminds you of that and I can see why it would upset you..
I also 'get' the feeling that you need your T to throw you a bone, here. You've worked so hard. The gesture of moving this thing at your request would have been important, made YOU feel important. I also understand when you say if he did it now it's too late - you don't want to have to beg for what you need from him.
Playing Devil's advocate... Are you sure your T understands just how triggering you find this item to be? Or is it possible he thinks maybe
you're the one being unnecessarily awkward, throwing a spanner in the works as an excuse not to move forward? Perhaps try to explain to him (again)?
