>is it the body-type, behavior, lack of life experience/innocence, or a combination of all three that attracts you to them?
>If an adult woman looked just like a kid, but acted like an adult, would you be attracted to her?
No, because it would be an act. Ideally, a woman can retain some childlike optimism for her entire life, but in the modern West where she enters the work force, has casual sex with strangers, and generally behaves like a man, all the genuine innocence that women should have is gone. And to feminists who call that enslavement, we should ask: Do children feel like slaves to their parents? On occasion, yes, but childhood is generally a wonderful time. The fact some men abuse their children, just as some men mistreat their wives, does not disprove the rule - overall it's a good system. This is also why Japanese women - who pretend to act childlike, but are as jaded as the men - are not the solution either. I really couldn't love a woman who is jaded.
So yeah, a lot of my interest in lolis extends from their innocence. Some lolicons take pleasure in defiling their innocence, but others like me simply love their purity, their innocence, and want them to stay that way. Someone like Henry Darger would be similar. You could say any form of sex makes a girl lose her innocence, but that really depends on which society you're in. Victorian England or Puritan America had a negative view of sex, almost like it was evil. We should really celebrate sex, but only in the context of monogamous, life-long partnerships. This way, the women will retain their purity, and sex will remain special to both men and women.
