I think the difference between Jessica and Nick and porn couples is that they each prevent the other from hurting themselves.
That, to me, makes me love them.
Yes, neither Jessica or Nick are Mensa Members, like you and I probably are, but what really matters is that they don't hurt other people, and they don't let each other get hurt.
They both have kind hearts.
I don't know how you can let your spouse work in the porn industry, knowing the odds of getting harmful STD's, and sleep at night. When I found out what it was all about, I was horrified that I almost went into it, and worse, almost dragged my wife into it. I would imagine Jessica and Nick would react the same way if they found out the realities of porn.
Instead, we watch documentary after documentary about Jenna Jameson, who whores herself out to any asswipe with a combover for $6000, and no one asks her about the diseases she has. Not that she'd tell the truth anyway.
