On the cheating thing...if a man (or woman) wants to cheat, (s/)he'll cheat, prostitute or no prostitute. I wouldn't blame the prostitute because a married man goes to her, I'd blame the man.

There's a company (possibly more than one) that helps people (men and women) cheat on their spouses and significant others. They have all kinds of thing set up to help cheaters get away with it. If you're a cheater and want your wife to think you're hanging out at a hotel when you're really partying away, you can give your wife a phone number to the hotel...only it's not to the hotel, it's to the company, who answers the phone as if they're the hotel (like, "Good morning, LA Hilton, how may I direct your call?"). They have ways to help you, the cheater, to hide your actions, and even help people meet people to cheat with.
