That has proven to be fairly incorrect. A lot of those guys may not be immediately aroused by masculinity, but they still like masculinity. Just because your dick don’t get hard doesn’t mean that’s not something you’re into to. Many of those men love sucking guys’ dicks or taking it up the ass from more masculine guys. They’re just scared to fully embrace that, especially on camera. Many of those guys also just see women as sex objects. They don’t really lean towards women when it comes to romantic, emotion, affection, relationship stuff, just sexual stuff and immediate arousal stuff. There’s way more diversity out here when it comes to “sexuality”, fluidity, the spectrum and human psychology and motivation.
While, yes, the whole straight-presenting, light-skin dudes being worshipped by dark-skin, unabashedly queer men does make me uncomfortable. Matt Ryan indulged that same shit for years despite likely fucking around with darker dudes and taking up the ass for years. They know that presenting as straight/straight-ish and being light-skin is a big advantage and they use it.
