Everyone has their opinion, but I can't help but laugh when I read a irrumatio fan talking about "vomit nonsense".
I suppose that somewhere you'll find a drag racing fan talking about "noise and flames nonsense".
Concerning extreme deep throat films with zero vomit, no doubt they edited accidental vomit scenes to clean it up for the mainstream audience.
Just because vomit is congruent with deep throating, it doesn't mean people are silly for preferring not to see it.
I like steak and hamburgers, but I'm not interested in watching cows get slaughtered.
There are certain things associated with deep throating that's universally appealing, that no one complains about.
A massive bulge moving up and down on a throat.
Tears occasionally streaming down her eye or eyes.
Gagging.
A specifically powerful cough, implying saliva or liquid went down the wrong pipe
Eye contact with an occasional gaze of worry or dread, preferably with a coinciding tear streaming down
extreme duration of oxygen deprivation, preferably demonstrated by servicing multiple cocks in succession without breaks
A genuine throat pie, verified with certain techniques we're all familiar with
Burping.
Constantly on the verge of vomit, without actually vomiting. You know? Her back arches, her tongue suddenly sticks out, and her throat bulges, but no vomit, preferably accompanied with a burp.
What do all of these things have in common? They're eye and ear candy for a sadist.
Believe it or not the sight of vomit is also eye candy for a sadist. But the ones who like it are the minority, not the mainstream.
So why don't we just observe and celebrate the sheer amount of degenerate sadistic preferences that we do have in common, instead of focusing on that one solitary thing that we don't have in common and celebrate our similarities.
And stop wasting time, trying to come up with clever examples of logic on why one should or shouldn't like vomit, and stop trying to convince people.
It's genetic. Your preferences are determined by your genes, not by logic.
I'm in the mainstream, but I don't wig out if there's occasional vomit.
EDIT: Evolution has equipped our brain with instincts to protect ourselves.
We have aversion to poop, because it's associated with disease/ death. The mere smell of it is unpleasant.
We've learned to properly dispose of a deceased person, because it's obviously a biohazard.
Vomit is not quite as dangerous YET, but it's associated with food poisoning, so our instincts go on the alert.
This is why scat and vomit are niche.
The majority of people have biohazard evolutionary alerts that get triggered.
Personally, I can't even begin to form any theory on why scat is even a thing. Where's the sadist element? It's 100% pure downside LOL.
With vomit, I can at least see the logic of being associated with sadistic elements.
But for most people the biohazard alert gets triggered hence rendering vomit a niche genre.
