Everything under fetishes (except for Bishounen) are strictly only meant for hentai (18 Restricted) and ecchi anime. In case of ecchi, it must be the main element of the show and not when there's only some of it, for example, there's some ecchi in Shinseiki Evangelion, but just because you get to see Asuka's pantsu doesn't warrant it to get the schoolgirl fetish category added. So be careful to which ecchi show you add fetishes, it's fairly straightforward with hentai, though. Overall, this category tree is to satisfy the needs of people with different fetishes, so they can search for what tingles their tangle; hence why this is restricted to hentai and full ecchi shows.
This is the only category in the fetishes tree that isn't restricted to ecchi. In most cases, bishounen goes together with shounen-ai and is mainly targeted at girls. Bishounen anime's cast consist primarily of good looking males with different personalities, think of it as the opposite to a harem anime, just with guys instead of girls and scratch down the ecchi elements. Bishounen anime usually have more serious themes and can have quite a lot of action in them. It should be pretty clear as to what certifies as a bishounen anime, so don't go adding it to every anime that has a handsome youth or two in them.
Almost completely exclusive to hentai animations. Any kind of female teacher will do, even if she only does home visits. Female teachers imply mature women (even if they sometimes look like schoolgirls) dressed in what women would typically wear when doing official business (like a blouse, pinstripe dress with side front slit), but of course, not limited to that.
Exclusive to hentai only. Futanari (a compound word meaning "two form" in Japanese) depicts hermaphrodites, intersex or other individuals with female body-types and sexual organs resembling penises, whether or not those organs are in fact enlarged clitorises, or they possess both male and female reproductive organs. Technically, the term also encompasses male characters with both sets of sexual organs, but these are usually excluded. To those who're not that good with technical terms, futanari = chicks with dicks.
Almost completely exclusive to hentai animations. A housewife is a mature woman (should be out of high school age) who doesn't necessarily have to be married in our context, but typically is. A housewife doesn't work (depending on context, she would be an Office Lady instead), however, since we're not as much down to technical details as we are of visuals, that restriction can be discarded if the character in question is shown mostly in home environment wearing leisure time clothing or a kimono and an apron can also be safely added to the bunch.
