Long "labia minora":[https://en.wikipedia.org/wiki/Labia_minora].

It can be [[long labia]] even if it's naturally small but "it's being stretched":[https://en.wikipedia.org/wiki/Labia_stretching]. (Example: post #2880082)

The medical term is labial hypertrophy. It's a harmless variation from female to female and it is quite common. The main deciding factor is genes, but puberty, chronic hormonal imbalance, and pregnancy can enlarge the labia oftentimes permanently.

The Felicio classification measures the stretched labia minora from its base: grade 1 being shorter than 2 centimeters; grade 4 being longer than 6 centimeters; and grades in between are separated by steps of 2 centimeters.

This grading has been defined without the regard of proportion, which is now commonly understood as a problem. Usually only women that have protruding labia minora past the labia majora consider functional (non-cosmetic) plastic surgery, and similarly [b]Danbooru tags the visibility or the degree of protrusion[/b]. This means that due to the outdated definition of grades, the by-the-book medical diagnosis might conclude the absence of labial hypertrophy even if there is a clearly present case.
