There are many things that turn me off in porn movies instantly and here is a sample list.
Reminder, it's a personal list not intended to offend anybody or judge their personal fetishes this is just stuff I see too much of and it instantly turns me off.
condoms ( ruins the scene for me )
cum dodging ( if you don't like cum then get the fuck out of porn )
big bush ( trim it or shave it, no power muff please )
hairy armpits ( shave them )
hairy ass ( shave it twice )
loud over the top yelling, moaning, screaming ( shut up bitch )
high pitch squealing ( shut the fuck up bitch, I know it's fake )
girls who look like they are in pain
fish hook ( stupidity )
intentional cum in the eye ( too rude )
fake cocks and cum
fake squirting
pretty much fake anything
bad boob jobs especially with deep scars
girls who look drunk or stoned or like junkies
anal fisting
scat
pee drinking
obesity
99 % of all midgets and or dwarves ( there are exceptions )
99.9 % of all shemales (0.01 % really are hot )
bi and or gay male anal sex, ( just looks so wrong to me )
clowns ( I mean WTF ? )
girls who look underage ( must be a lot of pedophiles out there )
granny's ( just can't see the attraction )
ugly guys that ruin the scene ( you know you've seem )
animals ( not only illegal but just wrong on so many levels )
torture or extreme BDSM ( sorry, not into pain )
amputees ( I end up feeling sorry for them, can't help it. )
lesions, boils, a lot pimples on the ass, cold sores ( they look diseased )
and my # 1 turn off in porn...
girls who look like they are just doing the scene for a paycheck
