"Technically," he added, "any time a person engages in sexual penetration in an adulterous relationship, he or she is guilty of CSC I," the most serious sexual assault charge in Michigan's criminal code.(via)
The anarchist case for fidelity:
So long as it worked, it worked, and if it didn't work it stopped being. It was not an institution but a function. It had no sanction but that of private conscience. . . .
The validity of the promise, even promise of indefinite term, was deep in the grain of Odo's thinking; though it might seem that her insistence on freedom to change would invalidate the idea of promise or vow, in fact the freedom made the promise meaningful. A promise is a direction taken, a self-limitation on choice. . . . [I]f no direction is taken, if one goes nowhere, no change will occur. One's freedom to change will be unused, exactly as if one were in jail, a jail of one's own building, a maze in which no one way is better than any other. So Odo came to see the promise, the pledge, the idea of fidelity, as essential in the complexity of freedom.
