>>2225483>>2230532I'll take a stab at this one. If anyone else wants to propose a competing theory, go ahead.
Gooning is porn addiction fetishized. As with any addiction, the longer you feed it, the more stimulation you need to feel the original high that got you hooked in the first place.
So let's say your porn journey started with solo women, skinny teens in this case. It won't be long before you'll over indulge this genre and it won't give you the high it used to. So then you're on to BBWs, maybe different races and ages, but still solo women.
That'll buy you more time, but eventually it won't be enough.
Maybe you'll move onto something woman-specific after awhile (their feet, their assholes, their piss, who knows). But more than likely you'll move to hardcore.
Hardcore introduces the penis; perhaps that was a line you didn't want to cross, after all, you're not gay or bi. But still, women alone isn't doing it for it you as much as it did before because you've seen so many of them and now you're desensitized. So you start jacking it while looking not only at women, but men as well. Breaking this taboo you had actually really turns you on. How deviant, to break your own rule, this forbidden aspect is really making your porn-high super powerful again.
And that works, for awhile. Then you get desensitized. But you remember what you learned last time. Push your boundaries, break your own taboos, and suddenly the high comes back.
So now it's not just women + cock, it's women + cock + kinky subtext. Maybe it's degrading or homo-erotic, but now you need some kind of extra layer of meaning. Being so far from where you started (totally hetero) and now being into being at least somewhat gay is a big taboo and really gets you going because it shows how far you've come in your addiction, how much it's changed you. And guess what? The whole community knows that and they celebrate it.
