i can’t find out what is my sexuality???

Asexual aromatic and Ты probably have a case of schediophilia

If the only people Ты have a sexual/romantic attraction to are animated ones, then Ты are Aro Ace and Schediaphillic. And in case Ты don't know those definitions:

Aro (slang for Aromantic)-

To have 0 romantic attraction towards anyone.

Ace (slang for Asexual)-

To have 0 sexual attraction towards anyone.

Schediaphillia (aka Toonophillia)-

To have a sexual and/or romantic attraction to animated characters. This attraction doesn't always involve the things listed, it could just be as simple as having a major obsession with/connection to cartoon characters.

Don't like anyone but boys in Яой anime. I think that just makes Ты a pervert, good job

That sounds ace to me. I'm an ace, that sounds like how I am sorta; like I find people (of both genders) attractive, but I don't want to дата nor have sex with them.

Well, either Ты haven`t found the right person yet, или Ты just are asexual :)

Well.
For one, if you're only like, 11-13, there is a chance that Ты just aren't interested in sex или dating yet and haven't hit that point in your life. (I didn't even know what sex actually was till I was 13 and wasn't interested in it или dating till I was 15)
It's best to just wait things out for now, if things don't change then yeah, it's probably what everyone else is saying.
But imo you're probably just too young to get it and Яой is just your first bridge into that stuff.
