I'll say what I said on the texted version of this…
On page 8, the patch covers and therefore replaces her vagina.
On page 13, it is clear that she no longer has a vagina.
(Although, for some reason, this version is missing page 13.)
This is not futanari. "Futanari" is not a synonym of "dickgirl". The "futa-" in "futanari" literally means "two" or "both", as in sets of genitals. If she has a penis but not a vagina, then she is a shemale, not a futanari. And yes, it matters, because it's part of the fetish for most people who enjoy this stuff. Please tag correctly.
