General: flashing
Images or animations depicting a character of either gender exposing part of their sexual anatomy to another character or the camera, an act colloquially referred to as "flashing". This can be done as an act of sexual foreplay between lovers in a couple or a simple act of exhibitionism, showing off one's body to a stranger for a kinky thrill.
The most common depiction of flashing has a female character exposing her breasts to another character, although images can also include a female character exposing her vulva or a male character exposing his penis and testicles.
Images of a character deliberately exposing his or her buttocks to another, whether or not it also exposes his or her anus and/or genitals, should be tagged with mooning instead.
