This girl looks like one of those trans girls with a huge cock. And before some clueless idiot starts talking nonsense, let’s get something straight: futanari has existed for over a thousand years — during the Asuka, Heian, and Edo periods. Historically, males with breasts were already classified as futanari even without a vagina, just like most Western characters today.

I’m a Republican, not an activist. I’m 16 years old and I like biology. There are extreme DSD cases where an individual has a 99% feminine appearance — feminine voice, natural breasts, feminine bone density, and delicate features — and yet is biologically male. Why? Because they have fully functional male genitalia.

So let me make this crystal clear: biologically speaking, anyone who produces male gametes and identifies or believes they are a woman is, by definition, trans — even if they were born with a 99% feminine appearance and, in some rare cases, a vaginal opening...

There’s a lot of misinformation about the term “futanari.” Let’s break it down clearly:

1. Historical origin and meaning:
The word futanari (二形 or 二成り) was born in Japan, but the concept wasn’t. It actually comes from much older ideas originating in China, strongly influenced by yin–yang philosophy and Buddhist texts.



In Chinese medical and religious records, there are descriptions of males with breast development, which were seen as a “mixture of yin and yang.” These ideas predate the term èr gēn (二根) — literally “two roots” — which classified individuals with both male and female sexual traits.

When Buddhism reached Japan, the notion of “dual nature” was absorbed and adapted linguistically into futanari. While the main focus was on individuals with ambiguous or mixed genitalia (what we now call intersex), from the Asuka period and especially during the Heian and Edo periods, futanari became a broad concept, involving not only physiology but also identity, performance, and gender expression.

2. The broad scope of the concept:
Japanese scholars who study this subject acknowledge this historical breadth. Futanari can be imagined as an umbrella term with multiple layers or subcategories, including:



futanari with mixed genitalia (intersex/hermaphrodite)

futanari without vagina (males with breasts and feminine traits)

androgynous futanari

male intersex

classical hermaphrodites


Another crucial point: when talking about modern futanari in Japanese hentai, the overwhelming majority do not display female reproductive function (for example, a functional uterus or the ability to become pregnant). These characters typically have fully male genitalia — penis and testicles — but a female body, which biologically corresponds to male intersex, not to functional hermaphroditism. This clearly shows how modern culture inherited the idea of sexual duality but centered it on the penis rather than full reproductive ambiguity.

3. DSD variations and biology:
People with extreme DSD variations (Differences of Sex Development) also fit into this historical futanari spectrum. In many cases, they present:



natural breasts

female bone density and fat distribution

delicate facial features and a feminine voice

lack of dense body hair

yet possess fully male genitalia


From a chromosomal standpoint, some may have rare variations — for example, La Chapelle syndrome, where an XX individual develops testicles due to SRY gene translocation. Despite their highly feminine appearance, they are biologically classified as male.

Historically, these kinds of bodies and identities were also encompassed by the term futanari in Japan, since they embodied the idea of “two natures,” a fusion of yin and yang, even without ambiguous genitalia.

In summary:

Futanari was never just a fictional concept; its roots are medical, religious, and cultural.

It has always been a broad concept, and yes, males with breasts and feminine appearance were included in it.

The futanari category historically and biologically covers multiple forms of dual sexual traits.

In modern hentai, most futanari characters represent male intersex, since they have male genitalia without female reproductive function.
