“I think there is this bias that women don’t cheat for sexual reasons at all,” Hertlein says.

And once you hit send, you no longer have control over what happens next.
The typical affair used to start in the office and move to a seedy motel room, but the vast reach of the Internet has brought infidelity into many couples’ homes over the past decade.

While men traditionally have been the more unfaithful sex, gender roles are reversing in some cases as more women experience cybersex.
