Hold on, I'm not sure we're talking about the same thing now. For reference, when I use the masculine pronoun in reference to no specific individual here, I use it in its historically established sense as gender neutral.
Here's a more in-depth explanation of common terms.
There are people who are born with physical characteristics that aren't quite male or female in the binary sense, but somewhere in between. While a few have both male and female gonadal tissue (testicular and ovarian), usually they lean one way or the other, and some don't even outwardly appear different than a biological male/female, but have some internal characteristics that combine the two. Intersex individuals with relatively developed male AND female sexual characteristics are extremely rare, and most intersex individuals are assigned whichever sex they are closest to at birth, and prescribed hormone and surgical treatments over the course of their lives so their bodies develop more closely to that sex.
The historically used term in English-speaking countries for intersex individuals is hermaphrodite. While seen today as perhaps insensitive, and no longer entirely medically accurate, the term intersex has not achieved a level of universal awareness in English-speaking countries, so you'll see it used pretty frequently.
The historically used term in Japan for intersex individuals, though I believe the modern accepted terms there are han'in'you or intersex (borrowed from English). The futanari we see in porn, with well developed female secondary sexual characteristics (breasts, body shape, etc.) and well developed male and female primary sexual characteristics (genitalia) are largely fictional.
