Am I an Asexual?(18 year old male)

Hi, and as you can guess from the subject line, I'm kinda confused about my sexual orientation.

First, while my friends like watching porn and talk about it, I simply can't understand them. Sure, I do watch porn, but I don't feel sexually excited by doing it. In fact, I am cutting down on watching them these days due to its 'cringiness'.

I got confused about it, so I tried another thing; watching animie girls and see if it can arouse sexual love towards them. But when I look at them, I only think they're cute, not beautiful. And by 'cute', I mean the same feeling one gets while looking at pets. I just looked at them an think, 'So that's what they call 'beautiful' '.

I don't think it's just a phase, like my mom and older bro said. So what do you think?
