Personally. I'd say top even if the lower half of the 'roo is rendered anthropomorphically. As for 'roo femmes, I described one as having a bit of cleavage that turned out to be pectoral muscles - her actual mammaries are in her pouch, as is expected (of course, I also suggested that the inner edge of the pouch opening is an erogenous zone).
Bottom. Hanging low. My tolerance for "anatomically correct" dicks ends with knots. Even those I shy away from, I've only drawn them when asked to.
It bothers me that a lot of people treat the subject of what dick to put on their animal people as a matter of right and wrong. If you want to put a weird penis on your creature say it's because you like it, not because anything else would be wrong.
hmmm... guess that would d'pend on the position of the character fer me.... balls overlappin' the cock has always been one'a m'fav positions... someone once did a pic of a roo upsidedown in bondage an had the balls still above the cock (so that it was underneath the cock from the viewer's perspective)... so m'fine with whatever inspiration inspires in ya :P
I like 'em weird, but if you go for top on an anthro, they've got to nestle comfortably to make the pic comfortable to look at; something like the Bad Dragon wallaby where they 'dangle' by six inches looks like it'd make walking or anthro-type clothes-usage 'difficult.'
Which explains why their 'model' for that, um, model is semi-anthro and doesn't wear pants, if I remember right.
(And as others point out - rubbing on/leaning on the sheath (or cloaca-mons or what-have-you) looks.. "*mrr*," but some sort of arrangement that's gonna *thwap* when you hop is going to evolve out pretty fast. Unless it selects for a race of CBT-fetishists...)
Normal Size-Top
Hyper-Bottom
If the legs and such are drawn more feral, top.
And THAT'S personal preference! =D
So, my answer is yes.
Double the work (kinda - really just the genital area) but twice the fun!
Cloaca and balls, man!
Anything else just looks stupid.

That said, on the bottom works better for anthropomorphics, say I.
