Things that Turn you off in Porn.

Everything. It sucks ass...

Fake boobs, when they show the guy's face, when she is faking it >.> i rather watch hentai than regular porn

Bearded Dwarf Penis

"Oh my." -George Takei

I don't like tenticles. I don't know what it is but it just seems unatural to me. I know in some clips they disguise the tenticles as penis shaped dildos but it just ruins the humanistic animal nature of raw sex. Good ol' rumy pumpy was supposed to be between a penis and a vagina, amungst other pleasurable items for girl on girl and threesomes and so on..

And anal sometimes turns me off... Huge glory holes inviting in humongous fake cock is not something I want to be watching...

Real people, especially Latinas,Caucasians, and Africans.

If I enjoyed porn I wouldn't be here.

At a point in time I enjoyed porn as I thought it would take a certain degree of professionalism to have sex on camera. I went around digging up blogs and interviews of adult actors and actresses and discovered they're just regular people and quite a few of them are in it just for the money. Even more irritating was that so many got plastic surgery to become popular. This was a long time ago when I thought adult actors/esses were as big as the camera made it appear.

Discovering that killed off all interest I had in porn and not long after I discovered hentai.

-Acrylic Nails.
-Obvious makeup. [metallic eyeshadows, non-nude lipsticks.]
-Sex noises that are inconsistent with their rhythm, or are faked.
-"Gapes". You know what I'm talking about. I don't need to feel like I'm about to embark on a long dangerous journey down someone's yawning chasm of a vagina/sphincter.
-Anything greater than 2 partners.
-Shaved male genitalia.

-Whenever someone says "Yeah", and it's not a response to a question.

Wayy too much make-up.
More guys than girls.
Old guys.
Fat people, male or female.
When the girl is attractive but the guy is gross. (or vice versa, for that matter)
When either person exudes that air of douchebaggery that is impossible to ignore.
Lack of any kind of actual love/emotion.
Freakishly large implants.

anal, super big breasts, ugly chick/fat chick, if its a old ass milf or a mature porn

I swear the way that came to my mind was like reading a doujin out loud.

Everything, except X-Art

You are sooooo wrong.

I hate talking, fake moans, fake dicks, strap-ons, and black girls.

Pretty much all of what was already said in this thread. That and seeing the dudes face. I hate seeing the pricks face.

old men with hairy balls

I'm kind of with the music thing and certainly when a cameraman won't just be quiet.

really long masturbation scenes

1. If the people having sex are old.
2. giant fake breasts.
3. when they talk while having sex.
4. When the cameraman focuses on the guy's penis.
5. When the Porno I'm watching has a "Plot" (Normally a shitty one).
6. And last but not least... when there is more talking then porn.
