LINK , good read about suitcase pimps and how they deal with their pw wives. You aren't a real man if you have a wife who does this, imo. My favorite was the second one, this guy (spray tanned ufc colin quinn)
A few of my favorite quotes from it
"Sometimes I think about it when she works late and I'm going to bed," he says. "It's not negative, though. It's more like, eh . . . " He trails off with a what-can-you-do groan.
"I don't look at it as sex," he says. "I look at it as a guy with his dick in my wife, but they're working and it's not emotional. She never orgasms in porn. That's for us. If it happened on the set, it would be a little weird."
