I was actually debating this. Futa characters are quite difficult to write because they don’t necessarily fit into a single gender. For my writing, I’ve decided that some characters could identify as a woman or a trans woman, but I don’t want to expand on that for now and will leave it up to the reader’s interpretation.
While “gay” in this context usually refers to man-on-man interactions, I didn’t think it would be appropriate to omit the tag... we do have a male character sucking dih lol.
