No attraction

I cant tell if someone is attractive or not. I mean, I guess I sorta can but it doesnt register for me. Like I'm pretty sure Angelina Jolie is considered pretty but I'm not sure. I've heard people say Brad Pitt is but I cant tell. I just dont get it. Like I just yesterday I told my friend this and when we talked I asked if certain people were considered attractive, like Michael Jackson or Brendon Urie or Prince, cus I just have no idea. Dont get me wrong I can tell if someone looks dumb or not but not attractive lol. Either way, wrether they are considered pretty or not, it doesnt make me feel one way or another about them because I legit get my personal bias from there personality. (This part may be TMI) I dont even use visual porn, I'm just not visually stimulated like that, I listen to audio porn. Is this odd? Are there other people like this? Who dont get attraction, not who listen to audio porn lol

Edit: it's not just celebrities, its anyone at all
