futanari

is the Japanese word for hermaphroditism, which is also used in a broader sense for androgyny.

Beyond Japan, the term has come to be used to describe a commonly pornographic genre of eroge, manga, and anime, which includes characters that show primary sexual characteristics from both females and males. In today's language, it refers almost exclusively to characters who have a gynomorph-female or overall feminine body, but have both female and male primary genitalia (although a scrotum is not always present, while breasts, a penis, and a vulva are). In rare cases of otokofutanari, instead of a woman, it's a andromorphic-male or overall masculine body, with a penis, a vagina, and muscles instead of breasts. In gyaku-futanari ("reverse"-futanari), instead of replacing a woman's vagina with a penis, replace a man's penis with a vagina (this never counts as a hermaphrodite; in English, analogous term for it is "cuntboy"). The term is also often abbreviated as futa(s), which is also used as a generalized term for the works themselves.
