In support of "notmyrealnick" I have to say that most people wrongly believe that the sexual life of humans only starts when they reach adolescenthood, Bronislaw Malinowski in his studies with savages(Book: The Sexual Life of Savages in North-Western Melanesia) showed that the starting age can be as young as 5 years old. But we in our modern society repress the children.

Edit: related to this is the (IMHO wrong) thought that underage humans cannot possibly give informed consent to sexual acts.
Edit2: Btw, when I speak about underage sex I'm thinking about sex where all the involved are more or less of the same age.
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
