Would the transfem counterpart to Androsexiness be Misosexiness or Femsexiness? And would non-binary be Enbysexiness or Neusexiness?
This is a very important conundrum
You are absolutely right, this is a very important conundrum.
For transfems both of those would probably be great options, but we also could have Gynesexiness. 
Following the Latin word andro in androsexiness. But to be completely honest, i’m not the most comfortable deciding which ones of these words would be most appropriate, as I’m not transfem. I think at the end of the day if this term ever would get popularized(I hope it does), I think it would be down to the individual trans person to choose which word fits their experience the best. Anyways you ladies are purely wonderful and I love you so much 
What I am most certainly comfortable talking about though is the words for non-binary people. I probably would end up mostly using Neusexiness. Mostly because I know other non-binary people that aren’t the biggest fan of the word Enby. I would probably also add the words Nullsexiness or Mutisexiness, for agender/gerndernull and Mutigernder folks respectively. Now, i’m still looking for a word for genderfluid folks, so if anybody has any proposals, I’m glad to hear it!
I really do like how this community has turned someone insulting transmasc by using the word Androhysteria in relation to transmasc talk about their oppression into “yeah trans people of all genders are really fucking sexy”, I love that we do this. 
So far we have:
Androsexiness: the unique way that transmasc individuals present (each one in their own way) their sexiness in relation to their transmasc identity
Misosexiness/Femsexiness/Gynesexiness: the unique way that transfems individuals present (each one in their own way) their sexiness in relation to their transfem identity
Enbysexiness/Neusexiness/Nullsexiness/Mutisexiness: the unique way that non transmasc/fems individuals present (each one in their own way) their sexiness in relation to their trans identity
Intersexiness: the unique way that intersex individuals present (each one in their own way) their sexiness in relation to their intersex identity
TDH trans people might find this a useful tool to describe their own sexiness. We are so often fetishized in the eyes of the cisarchy, this could potentially be a very good way for us to reclaim our sexual autonomy, free for the patriarchal/cisarchal regulations on what and what is it sexy. I hope somebody finds a use for these terms, I am WAY to ace to appear sexy. Not saying that ace people can’t, I just can’t.
