Adults should never, in any way, see children sexually, as sexual partners, as a source of sexual gratification and pleasure. Children, especially when they're prepubescent and young, aren't psychologically or physiologically developed to be sexual in a way that won't injure them, potentially even kill them. It can lead to serious psychological and physical trauma, even catastrophic injury to a child's body, leading to death. If you're proposing sexualizing children, and encouraging sexual behavior among prepubescent children, especially between adults and children, that's sick and criminal. Children shouldn't be burdened with sex, they should be focusing on other things.
