Is OTHER wrong in the post ? POST : I don’t know how to flag NSFW, I’m sorry if I mess up

So I am a university student 18 (F), I frequently hang out in a lounge for students that an acquaintance of mine 19 (F). I like her but sometimes she has troubling behavior and doesn’t listen when you tell her to stop doing something. The lounge is a pretty public place and is mostly great to hang out.

But my acquaintance has recently liked to show me NSFW material without my consent, mostly those that she has drawn or animated on MAYA. The conversation usually goes like this;

A: hey can I show you something I drew
me: sure
A: -shows me the pornagraphic material she drew-

Most of the time this porn is shown in a humorous way, but it just makes me uncomfortable. One of the porn she showed me depicted a teenager (low teens). I have told her multiple times that I’m uncomfortable with it and she just doesn’t listen. Once I said that I didn’t want to see something that she drew because I was working and she just showed it to me anyways.

I just want her to stop doing it, I like her as an acquaintance but what she does makes me uncomfortable. Would I be an asshole if I talked to a professor or Guidance counselor about this?
