Am I in the wrong?

My partners sister is staying with us for a couple of weeks. She’s using our study/pull out lounge to sleep on. I was sitting in there doing work and as I was packing up, I knocked something off the arm of the lounge. I picked it up (it was in a white silky case) it was a vibrator.

I messaged her and asked if she wouldn’t mind moving it off the arm of the lounge, and she got pissed off and wanted the study back. She didn’t say anything (except grunt out of frustration) (she’s 32 yrs old also)

She has no shame, and has also left condoms laying around the study which I haven’t mentioned to her. But after seeing the vibrator on the arm of my couch, I thought I should stand my ground and mention something so she stops leaving things laying around.

Did I do something wrong in asking her to relocate the vibrator?
