Yes it is more than likely a show being put on for just you. I have had this happen to me and I enjoyed the show for as long as I could. Eventually had to close my shower door and shower. I don't leave the door open myself but do walk to the shower stall naked and back to the locker naked. If your show partner sees you watching the show he may become brave enough to strike up a conversation and that might lead to a show at his place or yours. Or maybe not. Depends on you at that point.
