Nature

And i still think a lil girl should wait till puberty because that is natures way of saying her body is ready.

Even though puberty signals that one can sexually reproduce that needant be read as ready for intercourse as well, imo. For instance I think being "ready" for intercourse has a lot more to do with knowledge about it and just simply how the girl feels than what her body or age is. Plus when talking about intercourse I cannot help but think of the penis. Those come in all variations of size and shape, so I don't want to eliminate (theoretically speaking!!!) all men or boys from experiencing intercourse with a prepubescent girl because harm is presumed. Letting any young girl decide when and with whom she wants to experience intercourse with seems like a better option to me to aim for than just dismissing all intercourse ever because of interpreting a natural growth process.
