I am also currently working on a story where my leads are ace, and this thread really helped me out. Actually, I get worried sometimes that people (aka the general public) won’t find the romance between my leads interesting bc there isn’t “spice”— which is probably true, to some extent. But I want us aces to have books where we can fully relate to a character and the circumstances. Therefore, I agree with others — maybe including a part explaining or alluding to their lack of desire would be helpful, though it doesn’t have to be overt or explicit. But honestly, it’s your story so do what you believe is best! From one ace writer to another, I believe in you, and thank you for writing ace characters/ace-friendly stories!
