When do you go from straight to gay?

So when is the moment that you would consider yourself “Gay”? Like, does getting turned on by gay porn make you gay? Is it when you have your first cock in your mouth? In your ass? When you no longer want or are interested in vaginas? When you fuck another guy? Or is it when you have an emotional connection on a deeper level?
There are so many of us “Straight” married guys that suck dick or get fucked by other guys or who fuck other guys, but consider ourselves “Mostly Straight” I'm sure everyone's definition is diffrent, but we do some pretty gay shit and don't call ourselves gay.
