I hadn't considered this perspective, which is totally me showing my own arse here. I apologize, I was stuck inside of my own perspective a bit.
TBH I think it's not one a lot of people, trans or cis, think about. The gender binary is often rerealized, imo, to include trans people, but enbies just can't fit neatly into it at all. For most people, I'd say this is subconscious, just as subconscious heteronormativity still exists even in very queer people.
However, I did not intend to suggest that "writing women with dicks who aren't AMAB trans" is the issue, although I understand how I left that impression. There's clearly nothing inherently wrong with trans bodies, I'm just unhappy when they're used exclusively as fetish material. A woman with a penis doesn't have to be AMAB trans (no matter how hard I personally might find it not to try to map my own experience onto them), it's more important that they are a fully realized character.
I do get that, ABO etc can still definitely fall into the 1D character fetishization trap. There's definitely even ABO written by wlw that falls into that trap, tho I don't read it.
I was specifically using "trans feminine" and "trans masculine" here instead of "trans woman" and "trans man" in an attempt to more broadly include nonbinary identities, but I did not meet the mark. Even then my comment is still a bit reductive, I know, but getting things perfect is a bit out of my grasp, still.
Also, it seems like everyone's genitals aren't actually relevant to the manga, which is nice. I apologize for my part in continuing a discussion on that, as though it's okay to talk about other people's parts like this.
Honestly, I don't consider myself trans, really, my enbieness feels like its own category (tho many NB people feel their enbieness is trans, ofc). And tbh, it's hard to get the every shifting world of gender completely right, what's important is willingness to learn and update your perceptions.
