I curate about 5 or so lists of trans romance/erotic works here on Itchio (and regularly make blog posts about specific trans works in certain genres/niches) and yeah, I've heard the cry of "people aren't making x type of work at ALL!" a lot and it just isn't true. Yes, often times these stories are indie and "unknown" but... we have the power to change that! We have the power to uplift each other and talk about the work!
I appreciate your perspective and I wish you the best with everything!
