My biggest complaint about straight porn is when in a 2-guys-1-chick scene or a blowbang/gangbang is when a chick tries to jam two or more peni in her mouth(or any other hole). Or, worse yet, when she is giving two guys handjobs at the same time, she starts rubbing them together. You know how fingernails on a chalkboard feels to the ears? Seeing this has been scientifically proven to have the same effect on a straight man's wood.

Don't see the latter happen happen too often(as I usually avoid gangbang type video), but occasionally sneaks it way in straight porn. Last time I say this happen, I took a look at the box cover and seen these words, I kid you not, printed on the front:
