All of the issues you brought up are valid. Personally, I think you get what you pay for. I like well produced porn with attractive talent that's competently shot and is well lit. In my experience that's nearly impossible to find without paying for it so that's what I do.

As for the content of porn, the repetition thing is a problem. Like with any style of movie, you just have to find some that don't suck. The best ones I find employ a variety of angles to avoid that problem. That being said, guys have always and will always want to see penetration. We are visual creatures and we want to see every part of a woman but especially the *****. I happen to be a bi male so I can add that I feel the same way about cock in videos.

Even though this post probably makes me sound like some sort of porn aficionado, I am not an authority on porn or even a huge consumer of it. I just happened to spend some time awhile back solving the problems you brought up for my own consumption. Like most guys I know, I need just enough porn around for "maintenance", if you get my meaning.
