Ugh, you're right!

But there's a huge number of pages that need the other tag added; I guess it'll have to be done manually on a case by case basis:

covering_nipples -covering_breasts

covering_breasts -covering_nipples

And while I know it's not an argument for an implication (because others could be added later or there could be ones where they aren't properly tagged), covering_nipples male contains exactly one image.

...actually, I'm not even sure that that's a male. The picture is androgynous, and as I recall the character in question is a flat-chested female for part of the story. Most of the urushibara_ruka pictures seem to have been tagged male or female more or less at random. This is really something for another thread, but is there a policy for when a character has canonical forms for both genders and appears completely androgynous in pictures?
