Genitalia

Genitalia is defined as the sex organs, or any anatomical parts, which are involved in sexual reproduction, and constitute the reproductive system in a complex organism.

Genitalia and furry
Many furries that design their character's form to include anatomical parts use genitalia that's either human-like, animal, or mix of both. This is most commonly an issue between male, hermaphrodite and intersex characters, since the penis varies much more widely between species than the vagina.

In furry art, the depiction of the genitalia in it is what generally determines its content ratings. To some, the existence of genitals is the defining line between furry and funny animal art.

Penises
There are many artists that design their characters with a humanoid penis, many of which have it tucked inside a penile sheath (the equivalent of a human foreskin), with the inclusion of animalistic features. For example, canine characters may have a canine penis with a chisel tip and the process of a knot at the base. Felines may have sharply-pointed glans covered in soft barbs. Equines often have a comparatively larger penis, many with flaring, mushroom-shaped glans.

Kangaroo males may have a long, tapering, crooked penis, with their testicles either hanging above it, like an anatomically correct marsupial, or in a more primate fashion.

Vagina/Vulva
While there are many that utilize a humanoid vagina, there are some exceptions, such as the Y-slit vulva of canine furs.
