Where does cupiosexual lie on the Attraction Layer Cake?

Not saying I don't fit on it, but based on the descriptions of the sexuality layers, I don't see where cupiosexual fits in it.

For reference, the cake can be found here: https://cake.avris.it/

Also, being agender, the homosexual/heterosexual scale seems off-putting I guess?

Maybe there's a better thing for describing attraction out there, but the cake seems very two gender and allo/ace focused, rather than any actual nuance, while trying to give the air of nuance?
