macrovagina 

A vagina of extraordinarily wide caliber (diameter), usually demonstrating a canal depth that is just as impressive in magnitude (>7 inches). The labia minora and labia majora are usually spaced far apart, and the vaginal orifice, as seen externally while looking at the vulva, appears to be a round hole. During intercourse, a macrovagina can give the false impression that a penis is very small. Macrovagina is often demonstrated by putting large objects inside, such as fists, cans, or Louisville sluggers.

My penis is not small; she just said she didn't feel it inside because she has a macrovagina.

macrovaginal disorder 

An affliction where a woman's vagina is abnormally large or gaping.

My girlfriend's macrovaginal disorder made me feel like less of a man.

Continued fisting caused MVD (Macrovaginal Disorder) in my girlfriend.

You don't want to date her, she has macrovaginal disorder.

Microvagina 

A vagina small enough to allow a micropenis to fit inside of.

My micropenis would fit well in her microvagina, thank god!
