I have read a bunch of those and would not have called them gay comics, though in retrospect I can recall a queer character existing in the ones where I got past volume 1
In this category: Saga, Sex Criminals, Squirrel Girl, Giant Days, Strong Female Protagonist
I adore SFP and Giant Days tho, despite them needing more queerness
If "has a queer main character" counts, Agents of the Realm is really good (WoC magical girls)
