I think he originally identified as bi and was pretty comfortable with that, but as time went on he went with a “queer” label as he started to have a bigger preference for guys. Also I can see Sirius having casual sex with people but only romantically falling for them after being friends. Like demiromantic?I feel like Sirius is masc genderqueer but never really “comes out” like he just casually wears skirts and makeup some days and knows he’s the hottest no matter what and that those who matter don’t give a fuckput a Ӝ and a character in my askbox and i'll tell you my gender/sexuality/romantic alignment headcanons for them
