I'm an AFAB enby (bi-gender, female and male), and I have similar goals, and have used the term "female to hermaphrodite" to describe my physical transition. However, I ran into the difficulty of using the term "hermaphrodite" because it upsets those who are intersex. Apparently "hermaphrodite" is a term that historically was used medically for intersex people, and has become an insulting word to that community. I still think of myself I those terms, using the historical Greek references, I just try to not use it in forums where such persons might be present.
I have been on testosterone for a year to gain more masculine features, and I have scheduled modified top surgery (extreme reduction, but not all the way to flat male chest) in August. I also have a bottom surgery consult coming up in January, and plan to ask for metoidioplasty *without* urethral lengthening (pee through the newly formed penis), the most common of all FtM bottom surgeries, and it's rare for a surgeon to require a vaginectomy with this particular procedure. I don't care how I pee, sitting or standing, and even if I had urethral lengthening, I'd probably still sit to pee.
For those who say FtMs retaining their vagina is rare, no, it's not. For those who are transitioning transmasculine, either binary or non-binary, it's more common than not for those who go through simple metoidioplasty and retain their vagina and uterus, partly because many still want to have children. Unlike estrogen for transwomen, testosterone does NOT cause permanent infertility in most FtMs. It takes a few months, but most can still get pregnant and have healthy children. There are a LOT of pregnant transmen out there, only a few end up on TV.
If the enby/transguy selects urethral lengthening and/or scrotoplasty, about half of surgeons require vaginectomy/hysterectomy, the other half do not.. Those who choose full phalloplasty usually (but not always) also require vaginectomy/hysterectomy. It takes special effort to preserve the existing function with a phalloplasty, which is the most extreme of the multiple FtM bottom surgery options.
