I'm not expert, but I think dickgirl is a penis only (but body of a girl), whereas futa has penis and vagina? Not totally sure on that, though. I mean, I guess you could start a new game with Ash as a dickgirl and see what the result is when you finally have sex.
first of all, great update, finally some ash ass action
second, you can change ash on the laptop in your bedroom at any point during freeroam, no need to start over.
third, you are overanalyzing fictional futanari, futanari is japanese for hermaphroditism or androgyny, dickgirl
in my opinion, is the best english word for fictional futanari and atleast in unofficial english translations of japanese media it has been used instead of futanari, you are free to think of it as you do but lots of artists call their girls with dicks futanari regardless of wether they actually have both reproductive organs present, there are no rules for dickgirls/futas in fiction other than what their creators decide. it comes form the same people who anthropmorphize everything they see from pistols to battleships and food to whitewares, its simply not worth reading too much into it.
