Are There Really Double Standards On Cheating For Husbands And Wives?

Throughout history, it is been socially acceptable (in varying degrees) for a husband to have a mistress, but almost never for a wife to have the equivalent - a "mister"? Some say the double standard applies not only to cheating but also to politics, law, society, culture and even education. The author of an interesting article on this topic thinks these double standards are about power and control - about empowering men and dis-empowering women. She suggests that, as many of the laws on inheritance, contracts and other property have been changed, that the double standard is also slowly changing.
