OK guys, I've basically missed out on this whole debate, and I've read through most of the thread and there's so much here that I'm not sure I want to start addressing any specific issue that anyone has raised.
However, on the subject of porn, there is one thing that I want to say.
There is this website that I found, it is called ifeelmyself.com. I believe rather firmly that it is the best porn to be found on the internet. To the extent that I am comfortable recommending porn, I recommend it. It is an exemplar of how pure and shameless erotica should be treated on film and it is probably the only porn that I have ever been fully comfortable enjoying. Basically it consists mainly of tasteful films of women masturbating. Every now and then it has a film of a woman being brought to orgasm by her real-life partner or close friend (be they male or female) going down on her or fingering her, but the vast majority of the videos are solo. There are also videos in which these women speak to the camera or hold discussions with each other about why they're doing what they're doing, and what makes them comfortable with it, and stuff like that. It basically bucks every uncomfortable and disturbing trend that is associated with porn extremely successfully and, I think as a direct result, is way hotter than any porn I've ever seen.
I don't even watch the videos anymore. I just queue up a video, turn off the computer monitor and all the lights, and put on headphones. Normal porn is all full of "fuck me!" and "oooh you're so big" and really silly-sounding and not-at-all-erotic stuff like that, but hearing a woman whose mind is genuinely in the process of being blown (hurr) is something that will send me completely over the edge, and to be honest visuals just get in the way of my imagination at that point.
Basically, if I had a point, it would be that it IS possible for porn to be done right, actually totally right, and that kind of stuff really is out there if you're lucky enough to find it among all the dross.
