What doesn't suck about the majority of porn scenes these days? It's the same tired old shit over and over again. Some of my pet peeves:

(1) Constantly switching positions. Stay still, dammit!
(2) Stupid contorted positions, like the pile driver. Am I watching a Bikram yoga class, or fucking?
(3) Sasha Grey and yammering whores of her ilk. Put a ball gag on them, please!
(4) Visible staph infections, herpes, or other fucksores.
(5) Booty popping, especially when done by white girls.
(6) All the cheap-ass lingerie and stripper shoes.
(7) Gaping. Oh look, I have a dilated anus. Aren't I talented?

That's just a partial list. But hey, this is what the market wants, right?
