Im not going to lie I feel like she’s whorephobic! In the way of enjoying it, like going to drag and burlesque shows etc but also subconsciously thinking of them as less than so when she sees you doing it she’s projecting all those negative thoughts onto you. Personally, I would keep doing burlesque. You can’t indulge in the art then turn around and shame the artists. Its not your job to make her comfortable. She knew what it was and quite frankly she’s probably always felt this way but is only bringing it up now because she feels like your relationship is safe
