Demisexual

I think I’m Demisexual. I’ve never had a crush on anyone except for my close friends. Hookups, one night stands, and cheating seem impossible and down right stupid. How could you do that to a stranger? Sure, I’ve thought celebrities were attractive, but I connected more with the character then the actor. I know a lot of people don’t, but insta romance just seems impossible. How could you say you love someone in a few days, or hours, or even minutes? I honestly can’t tell if I’m heterosexual with standards or Demisexual. Feedback would be awesome.
