I'm laughing on how you got jumped on so quickly, four responses and mine makes five! Still it is deserved. Any professional worth their license will not say prepubescents have no interest in sex itself. They will say it isn't as intense as those who have reached puberty, but children do have an interest.

Also remember that the research is not culturally tolerant. Considering our culture is incredibly anti-youth sexuality. Especially for prepubescents. In fact, when searching about prepubescent children and an interest in sex you get responses about pedophilia, child sexual assault, and how to prevent children from being sexual. In fact I came across one book that said once children experience sexual contact in any capacity they will seek it out in a more goal oriented fashion and act more flirtatious etc. The book of course frames this as a bad thing, however it's what is normal. The book suggests that it could be because of a sexually open home, but that this is damaging with of course no source to that claim, that the parents are failing as parents and might need to be reported. That's insane.

So again, going by modern research and claiming it is a good standard is not the best idea.
