Is it normal to find mainstream porn boring?

Now I'm not saying that porn in general bores me or that I prefer sick, nasty sub-genres to get excited - definitely not!

But I do find myself vastly preferring amateur porn to mainstream porn.

You know what I mean - the main companies like Vivid, etc.

It's like they release the same video over and over again.. the "stars" all act alike - the women are all apathetic and stupid, like they're all clones - and it's the same scene over and over and over again with different people done in the exact same way..

It's like I'm watching a documentary explaining the physics of sex.. there is simply nothing else there!

How other men get aroused by this baffles me.. you'd have to be so horny that just the plain sight of a naked woman having cookie-cutter sex would excite you. I've never been that way.. there simply has to be something else.

Do you guys agree.. at least partially?
