Wives might be just as unfaithful as husbands, new research quoted by the Wall Street Journal Indicates.
A Kinsey Institute 1991 survey found 21% of men had been unfaithful to their spouse, against 11% of women.
In the latest institute survey, the number of men who had cheated had declined to 19%; while the number of women who had had an affair rose to 14%.
Naturally, the internet cops some of the blame.
"Social networks [a] another factor, if only by expanding the pool of possible partners," writes the Journal's Peggy Drexler.
"Emotional friendships that turn physical are the traditional point of entry for female affairs. It is now easy for those friendships to take root online. Some argue that social networks are merely an expediter and that cheaters will always find a way. Still, if you've never quite gotten over your prom date, today the chances are much better that you can find him."
