Which is mostly limited to those who have had addiction problems as well-- not all but most---I can think of maybe only one or two who DIDN'T have either horrible self-esteem issues, or had been molested as a child.
I knew one survivor of child porn, actually two, because I believe it involved her and her brother.--Screwed up-- and I mean I thought damaged beyond repair.
I have a friend who was prostituted as a child, she didn't act out in actual pornography, but in other ways, sexual and non-sexual.
Since I have only life stories to go by, I'm like you, I can take a women's word that this is what she wants to do, but my anecdotal stories paint another picture. Not only that, because I'm the way I am, I've always been drawn to people of different cultures. So when I hear about the export sex industry in the Philippines, for instance I understand for these women, it's not about choice, and it never has been.
On another note, I bought the "Book of lists" by Russ Kick. Among his lists "sex" lists are "Strange genre's of Porn Movies"
More telling is "153 bizarre and Revealing Spam Subject Lines Leading to Sexually Oriented Messages" Needless to say most of it involves pornography with women and/or girls, and sounds horrid. Along with the erection and/or penile enlarger spam, it paints a pretty good picture of what the porn industry wants the general public to see.
From my anti-porn feminist point of view, porn will always be exploitative and demeaning to women as long as we have patriarchy rule. End of story. I know that some feminist thought is that pornography would disappear if society ever equalized.
That being said, there are a lot of sex worker advocates and activists who are trying to change the perception of the "Adult industry" as well as increase awareness and safety. (Some of these advocate fall into the "pimp" category as far as I'm concerned, and nearly all reinforce patriarchal values, but not all.)
This, I can go for since these men and women, by choice or not are easy victims, susceptible to violence and disease. I personally don't think these advocates are making a whole lot of headway because of the exploitive and world wide nature of the industry, but there are making inroads in slowing the HIV rate, as well as other diseases. I applaud and support their efforts. Pornography isn't going away anytime soon. (And the ones you see on reality TV are probably at the top of the food chain.)
I was reading about this women and her organization when looking up porn stats. It's is an example of the advocacy I was talking about
