I'll state for starters that I wish to avoid making a new tag for cartoon anuses right now, a proper tag name fails me and I don't think "cartoon_genitals" fits.
post #877877 & post #836241 are going to be two examples. These are tagged "anus", but their design for the anus is an X; said images are not rated explicit for this reason.
Clearly, there can be discrepancies between X anus and an actual one, usually because it is not meant to be used sexually, or in some cases, suggestive. They are meant to be details, and nothing more.
So, should we rate X anuses, or O anuses, with the same skin color underneath (i.e., just X/O, no discoloration to make it look like an anus)differently, or should all anuses be tagged explicit, regardless of nature or design?
