If It was possible, I would want to have as little as sex characteristics as possible (Except the gonads), so I identify with Neutrois, which is basically the gender identity that (for practical purposes) corresponds to the nullsex sex. For practical purposes, I just want an estrogenized body without breasts, even if it’s not really the same thing as nullsex, it’s somewhat achievable with surgery and Estradiol. Doctors won’t let me though because they see non-binary as a cosmetic thing rather than anatomical thing.
