How will I know if I'm Ace or not?

I was thinking about this before but I dismissed it, but the thought came back again and I’m curious. I’m a straight autistic 19F who’s an ally to the lgbt+ community. I have no interest in ever getting married, I am currently single and I like being single (though I know someday I might get a bf if the right guy comes across me but still), I don’t ever want to have sex… ever. I’ve never got any flirts or anything from guys but just looks or compliments (nothing wrong with that ofc), I never flirted a guy a day of my life i only give them looks or I just think to myself that their cute etc. I’ve never cared about a man’s private part(s) (like eww). If I was in a relationship now, I wouldn’t mind kisses, snuggles and stuff just not sex. And I know some straight individuals who have the same/similar manner as I do but they don’t consider themselves as Ace while others on the other hand DO consider themselves as Ace. So I’m wondering if I’m Ace or not. I would really appreciate it!! Thanks!
