In Japanese, the word hentai literally mean ‘sexually perverted’ when applied to publications and other printed materials. Hentai are mangas (comics) and anime (cartoons) that have a sexual theme as the basis of their stories. There are several categories of type of hentai fetishes that are depicted in these materials. How an artist chooses to draw these sexual encounters depends greatly on the artists’ skill and the expectations of those who are interested in the particular type of story.
In ecchi hentai the characters are displayed in a ‘pin-up’ soft porn manner. There is little or no overt sexual contact. These can be either simple pin up images or long complicated love stories, but in either case crude or explicit sex is forbidden.
On the opposite end of the spectrum, tentacle sex is almost always about a demon or a vampire (male or female) who forcibly assaults an innocent female (or male) and has a sexually explicit encounter. The tentacles are a result of early stringent Japanese censorship laws that forbid the showing of the male penis. Many artists used penis shaped tentacles to hold down and have forced sex with their victims to circumvent these restrictions.
Some hentai stories are of a whimsical nature, where humor is the main emotion used in the story. Many popular hentai stories are about young boys and girls who keep finding themselves in humorous situations and end up having explicit sexual encounters despite their attempts to avoid them.
The most extreme type of sexual encounter in hentai occurs with the transsexuals (TS) and the futanari (dickgirls). The TS are basically females with male genitals (no female sex organs) who are usually shy and eventually find a young boy who they ‘break in’ and fall in love with. The futanari are girls that have both male and female sex organs and are surrounded by females who eventually discover the dickgirl’s condition and take full advantage of it.
