You kinky motherfucker!
I learned something new today thanks to you and wikipedia.
"Futanari depicts hermaphrodites, intersex or other individuals with female body-types and sexual organs resembling penises, whether or not those organs are in fact enlarged clitorises, or they possess both male and female reproductive organs. Technically, the term also encompasses male characters with both sets of sexual organs, but these are usually excluded.

Other common terms used to describe futanari characters are "dickgirls" or "shemales", although these are often considered vulgar and incorrect. (The term "shemale" is typically used wrongly, since an accurate futanari character possesses a vagina. Shemale is considered a separate genre by many futanari fans). Futanari, along with "newhalf", are more polite terms having come into recent use, with futanari tending to refer specifically to actual hermaphrodites and "newhalf" tending to refer specifically to characters with female bodies but only male genitals."
