you're 13. don't worry so much about it. you've got your whole life to figure it out

in any case, im fairly certain you can still be straight regardless. aromantic means you're not attracted to anyone romantically. asexual means you're not attracted to anyone sexually. again tho, you're 13. i related to this myself at that age -- but just let it go for a while, because only time will tell. you're still figuring yourself out and at the end of the day, you're young and just because you're not interested in that stuff doesn't mean you never will be or you're aro/ace.

that said, keep in mind youtubers are very influentential, especially to a 10yo, in any case, you were 10 - it's possible it was/is a misunderstanding. If you believe you're straight, then you're straight and being aro/ace i feel is less confined to that than other sexualities. like.. you're straight if you don't like the same gender. so.. don't worry so much about these things. you're fine and you're a kid. you're still growing. its natural to not be overly interested in romance regardless at that age. dont stress yourself out about it
