Whether it's POV, or a background character you should always add this if a singular female is present in the image, however this tag does not imply mentioned character's or offscreen character's that just so happen to be a lady
However if the lady has a shlong, you should tag futanari! Or if the lady doesn't seem like a lady at all, then it's a trap!
The following tags are aliased to this tag: 1girls (learn more).
