Hi,
To quickly answer your question, your wife is not a 'whore' or a 'slut'. I'd have to say that she's a 'dumb whore' based on the fact that if she's even close to a decent piece of ass, she'd get paid.
Sir, I think you have the wrong idea about this business. If you think you pick and choose what couple or partner the two of you are prepared to work with, well, you're very wrong. This business is about fresh faces, quick turn-around and usually no limits. I suggest you take a few bucks, invest in a decent camcorder and submit some footage to Home Grown Video.
