A human character with no clothing on such as a male, female, intersex, or herm. A nude human may be naked because they're showering/taking a bath or getting out after they're finished, or having sexual intercourse for example and can be an anon character or faceless that may used as a self insert. Just because a human character is nude doesn't necessarily mean a post with this tag should be considered explicit, as the human character may have their gential region covered/not onscreen, or a featureless crotch which would be considered questionable or safe depending on the context.
