- When either the guy or girl hocks a loogie (spits) to lube up the dick or pussy. That just kills it right there.
- fake tits (unless they are so perfect that its hard to tell)
- small dick. Don't know why but even if the girl is a perfect 10, I would rather see her dance solo than watch a tiny dick fuck her. That's why I cant watch Thainee movies. She is hot as hell and even fulfills my fetish of tiny women, but her boyfriend literally has a 4" pencil dick. Its awefull.
- When the guy REALLY goes limp. I'm not one of those idiots that can't tell the difference between a downward curving hard-on and a dick that's really not fully hard, but when the guy has to grip the base of his penis to penetrate the pussy, that really sucks.
- Bad camerawork. It doesn't happen often, but there are some dream match-ups in porn that were ruined by a totally incompetent cameraman. The one that comes to mind for me is the Shane Diesel scene in Desparate Housewhores with Mya Mason. Wow that scene had potential but the cameraman totally botched it.
- girls that are obviously dodging interracial porn. yeah I know its strange, but there are some hot ass actresses that I have been following, hoping and praying for an interracial scene (or at least a scene with a really huge white guy) and the longer they go, the more frustrated I get. After a while, when I come to the conclusion that they have sworn off black men, I am just turned off by the sight of them. Its weird.
