So the tag avian_penis gets used when an avian has a penis. Yes, that sounds very obvious and like the opposite of a problem. But the thing is- most birds do not have penises. Most of the images tagged with avian_penis are not ducks, ostriches, or vasa parrots. The penises depicted aren't modeled after those birds' either, but are just generic tapering penises.
Fantasy and speculative penises are not tagged. There's no dinosaur_penis or dragon_penis since we don't have anything to refer to for what it looks like.
My question is if this tag, which is continuously misused, should exist at all? Would it be better to only use tags for the exceptions like duck_penis or ostrich_penis?
