I have a few Sakura ones, they are decent, but mainly the h-doujins are about Hinata (bloody japs and their fascination with shy planks). And yeah there's a whole lot of Anko too, which is too bad, because Kurenai is much hotter. By the way those homosexual doujins are not called hentai, they are called "yaoi", and you should indeed steer clear of it if you value your eyes.
