Need some info

hey everybody, im writing like an essay on hentai and need some information or history on it, info on any public support or psychological studies would be nice, and anything else, i would appreciate any info

im gonna post this in a bunch of forums and stuff to try to educate people and stuff

i was maybe hoping for something else than just Wikipedia stuff, ive read all that, are there any reports on psychological studies out there? or maybe news articles and stuff
