After mulling this over for a bit, the answer is obvious for me.
I am choosing… n-n-no porn. But I don’t like it. Not one bit. As a matter of fact I don’t like this game, or you! 
And believe me, I am going to find some way around this!
You drive a hard bargain, but porn drives a harder one. And since there are things like Lingerie Football and Naked News, I figure I won’t be totally out of the loop.
Hell, I get bored with porn now. If it’s all or nothing, I’ll choose nothing.
I don’t understand the hypothetical.
Do you mean that (assuming I opt for “always porn”) whatever I view will be experienced by me as pornographic, versus (were I instead to opt for “no porn”) that nothing will seem pornographic to me?
Or do you mean that material I attempt to view will be magically swapped out for some definition of porn if what I selected was not already pornographic (or, in the other case, swapped out for non-pornographic material if I attempted to view porn)?
And in the latter of the two interpretations, whose definition of “porn” applies here? If I opt for all porn all the time, and it so happens that what arouses me is Coldwater Creek and J Jill models showing off the latest line of blouses and whatnot, do I get the fashion models or am I condemned to watch unclothed women being spritzed with guys’ ejaculate and looking bored whie giving blow jobs? Reciprocally, if I say “no porn for me” will I never again set eyes upon any image or movie footage that would arouse me?
Sorry for fighting the hypothetical, but I’m sticking with the status quo. So, if anyone needs me I’ll be . . . in my room.
To address your question of logistics: things will be swapped. If people around you are watching Walking Dead, you’ll see “College Anal Party 3.” If you go to Politico.com, you’ll find yourself looking at the Asian lesbian channel of PornHub.
As far as your own personal arousal experience goes, the definition of “porn” for this scenario is what is typically considered porn or “not decent” by our society. If watching squirrels bury nuts is the only thing that revs your engines, consider yourself lucky in this hypothetical; so if you choose “No porn,” you’ll still be able to watch squirrels bury nuts to your heart’s content. This is only about watching or not watching society’s “definition” of porn/sexy adult content/nudity/erotica/etc.
I simply could not give up 2 Broke girls or Mike and Molly. So no porn for me.
In light of that helpful clarification, “no porn” for AHunter3; won’t miss it a bit.
So you are giving up Two Broke Girls and a Cup, and Mike and Molly and Mark and Martha and Manuel and Maria.
As for me, I would have to pick “no porn”. I thought of what it would be like to watch a Hillary-Trump debate if everything were porn, and I would never survive.

Do re-runs of Top Gear count as porn?
When is this all or nothing change going to take place? I’m going with nothing, but if the change is happening soon, I want to get my fill in before it is too late.
I am a male. Whether I look at porn or not, I constantly see it, this poll makes no sense.
When correctly viewed, everything is lewd.
I have seen all the porn on the internet and frankly would find it refreshing to move onto other things. Most of it is reruns anyway.
It would be a much more challenging hypothetical if you were restricted to viewing your own personal ideal niche of porn. Like, say you need this complex 27-term search query to find exactly what you need. Suddenly that’s all you see every day. Do you do it?
Like, if you tell me that 50% of the porn I watch will be men doing it to men, then no question. Bring on the James Fenimore Cooper. But if it’s <my apparently niche thing>, then that’s a a more challenging question.
