Not who you asked, but I feel it’s more of a social thing in myself. HRT has biological effects, but I don’t think I’d be doing it in the first place if gender wasn’t such a construct to begin with. I believe the sexuality changes are mainly social as well. There’s the transmasc meme that T makes you more gay, but I don’t think it makes us gay so much as make us more attracted to gay/bi men who actually validate our gender identities, whereas pre-transition, many of us avoided straight men who simply viewed us as female.
It’s played at shops and on the radio with Christmas music though
