Most people into it dont actually like it for the smell only crazy people would like it for the smell, its just like facesitting if a ssbbw face sat you, you would feel like a trucks drove over your face or like an elephants foot was on your head basically it would be extremely painful to be under it buuuut on video an ssbbw smothering someone's face with her ass looks amazing. My simple point is, a lot of what people like in porn cant always be translated into real life unless your mind is actually broken. very few peoples mind are completely broken like that but as long as it looks good in porn many more people will watch it and pay for it. as for scat, farts, feet, armpit and most smell related porn i personally believe the only people who would like it in the real world are those who have likely already experienced it in the real world and liked it from their first experience before they experienced it in the porn world.
another basic idea is Anal porn. at first it disgusted me then i saw sarah banks doing an anal scene with mike Adriano and the POV looked fucking amazing then i saw mike do the same type of scene with Lisa ann and bella bellz and many more and now i have a 600gb collection of it, but would i fuck a women anal ...... nope the smell of shit coming from her ass would make my dick go LIMP immediately. Basically Porn is just fantasy
