Any adult fiction with ace characters will be listed here!
For these purposes, “asexual” or “ace” refers to any character who is or could be (with reasonable evidence) anywhere on the asexual spectrum. In other words, graysexuals and demisexuals count too! Also welcome are asexual characters who simultaneously identify as gay, bi, trans, or anything else.
Bonus points for anyone who finds an asexual character who is of color, disabled, or from an under-represented culture/religion/nationality. Sadly, those are some of the hardest to find.
