Half your age plus seven is the golden rule. You're fine.
Warning: this post is completely uninformed.
Snafu do you mean endemic in that it is fundamentally characteristic of our species, or that it is an isolated characteristic of our species? I assume you mean the former.
Our species? No. Men are far more likely to demonstrate pedophile behaviour than women, so this might actually be one of those cases where the label 'man kind' is actual.
I can completely understand the tendency from a evolutionary perspective: sex costs the male very little, and in return for this behaviour he is rewarded with the off-chance of successful offspring. Otherwise, it could just be a byproduct of a successful reproduction strategy (pork everything that moves).
I find it interesting lurking on 4chan and observing the debates between anonymous pedophiles (who generally claim to be inactive, but into CP etc.) and the moral fags. The pedophiles almost always present a much stronger argument than the people society would label right. Question: if someone has a sexual attraction to children but does not demonstrate this in his behaviour, does that make him a pedophile or something else?
It could be a byproduct from relative age attraction, or the lack of it in some people. If I am expected to be attracted to people around my age group when I am 12-14, and to not grow out of this tendency, then pedophilia would be a possible result.
I'm not sure on the stats for fetishism and pedophilia. Is it possible fetishism is an umbrella term under which pedophilia sits? I believe (don't quote me on this) that fetishism can be directed at pretty much anything and is a learned behaviour, this could include children
All speculation
