How to understand if I'm aroace or aromantic

Hello everyone. I'm certain that Im aromantic like 99% because I'm not interested in having romantic partner and never was in love. I only wanted to be someone's best friend and special person in my friendships, but when i tried to imagine kisses or something more (i thought i had crush so tried to understand what i felt to them) it felt wrong and made me feel bad cause it's not something i wanted. I also was in relationships several times, but first time it happend when i was kid and i don't remember fully what i felt. And after that somehow i just ended in relationships few times. I guess because i liked the person as a friend and they confessed me and i thought "okay then it might be a crush". But i don't think it was because i didn't want to imagine romantical stuff with them and the only "romantic" thing was that we called eachother with cute names and sayed we in relationships lol

But for the ace part, I'm not sure what to think. I used to think that I'm bi/pansexual. But i have low libido and most of time i don't think about these things. I'm not interested in having sex with someone and have never been. Still i can see someone attractive (when i next to someone i find attractive i feel something like a thrill of excitement) and dont want to do anything with it at all. And I've always been put off by the idea of sex. I used to think that something wrong with me and even had paranoia that somehow something i dont remember could happened with me in the past and thats why i felt this way, but it's impossible.

Labeling is important for me because i don't want someone to see me in some romantical / sexual sence. And i also want to understand if something is wrong with me or it's something that happens with some people and is okay
