You don’t need to fit perfectly to a definition of asexual to call yourself ace.

You don’t need to fit perfectly to a definition of aromantic to call yourself aro.

You don’t need to fit completely into the definition of asexual and aromantic to call yourself aroace.

Demiromantics can call themselves aro, greysexuals can call themselves ace. There’s no reason to gatekeep neither aro nor ace. These are both spectums and all of us can use them if we are on them.

You can also be aroace and something else, like aroace lesbian and aroace ply. You can define your orientation solely by other types of attraction than sexual and romantic attraction.

You are valid, you can call yourself these things, I will respect this and so do many others.
