hi!! great question - i know people are really just into a/b/o for the smut 90% of the time and i’m a sfw author, but i actually LOVE using it as a statement on sexism and gender stereotypes hahaha so that means i’m very flexible. i don’t think i’ve ever done two a/b/o fics with the same “world rules” if that makes sense? like in all of them i think the secondary gender mechanic works slightly differently depending on the angle i want to take. all that to say i really have no set preferences - i can and do enjoy writing any member with any secondary gender :)
