According to the artist, she is a boy (not a futa/shemale).
"In the context of anime imageboards, ‘futanari’ (双成り) literally meaning “made of two kinds”, is a fetish that depicts female characters with male genitalia, or both male and female. It is not related to transgender/intersex, but is purely fantasy-based." /wiki_pages/3589
Well... According to the definition of futanari... That's what we see here. Female character? Check. Dick? Check. Testicles (although not required)? Check? Observable breasts? Check. I mean, whatever, if the artist wants to label it FtM or whatever, I'm not saying that they can't. But this is a futanari. And should be tagged as such in addition to that.

As per Danbooru's tagging standards I would say this counts more as newhalf but technically ftm + manboobs does also apply so I'm not sure it needs to be changed
