A spectrum between gay and straight? What? Like kissing with eyes closed vs open? I don't believe in this spectrum of yours, but tell us where you are along it.
Bullshit. At least not among males. What you witnessed was not a change, but a coming out, something for which you are evidently long overdue, judging by your feverish preoccupation.

Honestly I tend to be hyper masculine. IOW: I see people like you and I see pu$$y written all over them and their mannerisms regardless of their external genitalia.
BULLSHIT, he decided to switch from normal sex to perverted. I actually know another guy, though not personally, that openly/publicly admitted he CHOSE to suck dicks and take it up the ass. He later CHOSE to stop it.
I am not a homophobe. However, I am drawn to irony. And here you are. I just want you to extend your own arguments to their natural conclusion. However, you truncate them when they become inconvenient.
