Because humans are inherently flawed. The Demiurge created us, and as such, humans, along with the entire material illusion of the Universe, are categorically evil. We find things animalistically sexually desirable that we should not according to modern Christian fundamentalism. We've raised the age of consent up to 16 in the U.S. when it used to be as low as 10 and the screaming masses of women want to vilify men who are attracted to young girls and boys in order to maintain their dominance over the Western sexual market, for if these young people were claimed early and saved from the sexual degeneracy that plagues the internet, and instead reproduced children, there would be less chance that the West would collapse.
In short, you're a sicko who's the product of the Demiurge. You were created with flaws because the creator is flawed.
