I prefer pornstars live and in person. The videos are fake. The people are more real and interesting behind the scenes.
I've met a few pornstars, strippers, and others who work in the adult industry, so for me it's not a faceless thing. I've made some friends in that field. There's a photo of me with a blond pornstar on my Facebook page that was taken in January. I also spent time hanging out with Johnny Soporno and his g/f Violet Marcell, and they came over to our house and hung out with me and Erin a couple times. Google her name if you'd like to find her site (explicit).
I really don't know how the adult industry works on the inside, but the people I know who work in the field don't seem to mind it. In fact, they seem pretty happy with the high pay for doing something they enjoy. I have to admit I was amused, but also impressed, by the time and energy they spend working on their skills.
If you like watching porn, enjoy it guilt-free. If you don't like it, feel free to diddle yourself w/o it, or get someone else to help you. IMO having a partner is a lot more fun than watching a video though.
