Same here.
Before I knew about my aromanticism I told a friend that I never had been "in love" so far. She was a bit confused and asked me how I could know that I'm a lesbian when I never had a "crush" on a girl. My response: "It just feels right to call myself lesbian."?♀️
To cut a long story short, only your heart knows how you identify. If it feels right to say "I'm aromantic", you are aromantic. If it doesn't feel right, maybe you aren't or it's not the right label for now but maybe the right in the future or in the past. Or you doesn't need a label at all.
