Luckily for me it didn't take long for me to accept myself.I spent a few nights on google finding and researching things and almost instantly realized I was aro. I found asexuality but at first I believed I was too young to be ace then I just decided to use it and see where that takes me. Whenever I question whether I'm bi or gay or some other orientation I ask myself if I like girls/boys and it's always an instant no. I've stuck with this label for 10 months now and I'm really confident in it. I'd just research and if something feels right try it. I thought I had maybe 2 crushes in elementary but looking back I just thought they were cool and wanted to be friends.
I agree it does sound like aesthetic attraction. Aesthetic attraction is tricky but something I saw on a video once about aesthetic attraction is if you think someone is pretty compare it to a nice bookshelf or something really pretty if they kind of feel the same then it's probably aesthetic attraction.(I probably butchered that explanation but I hope you get the idea.)
