Your comment doesn't make sense paired with this essay. To be sexualized means that you're seen as a sexual being who could be having sex. This is separate from gender. We assign gender to children at birth. When we say, "What a pretty girl!" to a three-year-old, most of us are not sexualizing her. When we say, "What a strong boy!" to a two-year-old, we're not saying, "He looks like he'd be powerful in bed!" One's sex is different from one's gender and both are different from sexuality. https://www.genderbread.org/

We do know who we are at age 10. We don't know at age 10 who we will be at age 30, and those are two different concepts. Who we are might change and expand as we age. We might change how we feel about who we want to have sex with—and that can change for a lot of reasons. We might also change how we feel about our gender. For a lot of reasons. And this is okay. There's absolutely no reason besides ideology why we should have to stay the same people forever or why we should have to suffer living a life that is interpreted by and proscribed by other people. That's not freedom.

But coming back to your comment about sexualizing children, yes, we should not do that TO children, ever. EVER! We shouldn't depict children sexually, have sex with children, flirt with children, say suggestive things to children, ask children about their bodies or sexual thoughts. None of that, ever. It's profoundly wrong and disgusting.

But children can sexualize themselves. It's a natural part of sexual development that before we ever engage in sex with other people, we develop sexual interest and we explore that in our own minds and with our own bodies and at different ages. Young children do this. I know people who were never sexually abused who nevertheless had sexual fantasies at age 7, 10, 11. I know people who never were sexually abused, who always felt safe, and who first masturbated at 6, 10, 11, 12.

So, I just don't see what you're trying to say and I don't see any logic you can draw from to justify what I think you're trying to argue.
