Futanaria Definition
Futanaria just like anything hentai comes from Japan.
The word simply means hermaphrodite. By definition futanaria is directly tied to the world of anime and manga porn and features girls with penises also dubbed dick girls. Some even refer to them as shemales even though in reality, they have both pussy and dick.
When futanaria porn first started surfacing anything or any person that had feminine and male characteristics was labelled as such. Later as the niche evolved it became quite popular to showcase futanaria characters who have their female and male parts enlarged or made to look bigger than it actually is.
This fetish is very popular with anyone who likes anime porn and hentai cartoons. The characters may appear in clothes with their genitals showing through, or totally nude engaged in some sort of explicit innuendo may that be hardcore sex with one another or self satisfaction like masturbation or titty play.
