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

Asexual aromatic and Du probably have a case of schediophilia

If the only people Du have a sexual/romantic attraction to are animated ones, then Du are Aro Ace and Schediaphillic. And in case Du 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 Yaoi anime. I think that just makes Du 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 datum nor have sex with them.

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

Well.
For one, if you're only like, 11-13, there is a chance that Du just aren't interested in sex oder 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 oder 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 Yaoi is just your first bridge into that stuff.
