Like I said, I don't think they actually went back and actually rewrote any of her scenes when they changed the character's dick, so shit's wacky for the time being. Hopefully that gets fixed some point down the line.
It is technically re-written, at least the first time she sees MCs dick, it's just re-written in the weirdest way possible.
Basically, they wrote it so the MC isn't "hard" enough for his dog dick knot to inflate. But the rest of the dialogue carries on like he just doesn't have one, which only makes sense if you know the MC had a human-shaped dick originally before the patreon poll.
What they should've done is re-drawn the CG so the MC's dick is still in it's sheath and he can't get hard. Either because he's nervous or because he's not used to his host body. Either works.
Then replace all of Roxanne's "weird dick" teasing with "limp dick". The drink could then be said to just relax/make you horny or something, but honestly I would just get rid of it and re-write all of the "fool around in the woods" parts to reflect the new canon.
