I never really cared for romantic scenes on movies. I didn't dislike them, but didn't care, except when it started to compromise the quality of the movie (or what I considered "quality" at the time). I really liked and still like Disney movies, but I thought they were exaggerating about love, since it is a cartoon and fairy tales anyway.
The biggest difference was how I didn't care about relationships during school. I barely remember in high school my classmates commenting something about going to parties to "catch"/"stay with" other people ("pegar", in Portuguese, and I still don't know exactly what this means).
Mostly I didn't care, or notice. I didn't think about me having any kind of relationship. If it happened someday, cool.
Only two years ago, when I stumbled on the concept of asexuality and aromanticism, I stopped to think about it. And realized these labels fit me.
