AsexualErotic or AceErotic.
Meaning: Being on the asexual spectrum and having a stronger connection between sex and sexuality than what is typical (say: only experiencing sexual attraction after having sex with someone, preferring sexual relationships over romantic or platonic despite not entirely experiencing sexual attraction in the normative sense, etc).
AceErotic Flag Idea:
Referencing the flag for allosexual (from pride-flags-for-cishets), an asexual spectrum flag (from Potion), and a fetish pride flag (from David Jatko in 2019, seen here). This reflects my own experience with being AceErotic (I might actually make the shorthand for that aerotic, pronounced ay-erotic, for ease of saying that verbally and spelling it, but I’m not sure if that makes sense to you, the reader of this).
