I think the romantic element is linked to desire for intimacy of some kind or other, and is there to some degree in every friendship, but when that becomes a “romantic attraction” usually varies and honestly is defined in hindsight more often than not.
So, not knowing is normal. If someone is pressing you to decide, they can definitely wait.
Yeah this is a favorite pet theory of mine as well, partly because I like imagining guys like Andrew Tate protesting being labeled “trans alpha” or whatever, but also because it’s just a fact that many cis people experience a form of gender dysphoria and commonly seek hormone therapy for it at early ages.
I’ve found that comparison usually clicks with uninitiated cis people immediately, even when they’ve only heard othering and alarmist narratives up to that point.
