Way I saw the tag, futa_on_male was just a shorter way of expressing "futa_sexually_engaged_with_male". However, the wiki currently redirects to male_on_futa, distinguishing the portrayed dominance of such engagement.
I'm thinking this is unnecessary.
(This brought to light when I went to add "ふた×男" to the futa_on_male wiki.)
Someone wanted a distinction between the male penetrating the futanari girl and vice versa.
I would tend to lump such pictures together personally, but I do see the difference as significant enough to merit separate tagging as the two have very different sexual overtones and may appeal differently to people.
Maybe we can just spread femdom onto it? We'd end up with femdom -futanari and futa_on_male femdom (which itself reads redundantly, given the current separation), but right now the relevant images don't seem numerous enough for it to be much of a problem.
...I'm really at a loss here, with how the tags are phrased.
EDIT: Unless we're talking about male penis in futa pussy. But then, wouldn't futa_on_male vaginal suffice for that? Would pegging qualify on futa penis in male anus images?
But then how do you separate images where there's clearly a one-way relationship from one where it goes both ways?

What about images in which a guy is going anal on a futa girl? Or images in which it's impossible to tell from perspective?
Would pegging qualify on futa penis in male anus images?
Yes. The wiki for the tag already states that.

The problem for me with these tags is that some images simple don't make it clear which way the relationship goes, particularly images in which sex hasn't started yet or in which other sexual acts like fellatio are involved.
e.g.
post #23172, submissive shota & submissive girl about to have sex
Do futadom and futasub work as ways of distinguishing the sexual role of the futanari girl, or does anyone have a better idea (for example, to avoid confusion with femdom)?
That second has no posts, but either case could be handled, as suggested by BTI, new dom/sub tags. However, I feel the pairings themselves would best work grouped with their kin.
Wouldn't the "cross" naming scheme be identical to the "on" naming scheme? From my understanding the "cross" system's general form is <Dom> X <Sub>, which would make it identical to the <Dom> on <Sub> naming.
