INTERESANTE: Blame affairs on evolution of sex roles:
Tolerance for male adultery is certainly at a new low. In letters and diaries written during the Colonial and Revolutionary eras, men routinely bragged about their extramarital conquests -- even to the brothers and fathers of their own wives! In the 1850s, it is estimated that New York City had one prostitute for every 64 men, while the mayors of Savannah, Georgia, and Norfolk, Virginia, put the numbers of prostitutes in their cities at one for every 39 and 26 men, respectively.
As late as 1930, Somserset Maugham's play, "The Constant Wife," was considered shocking because the heroine confronted her husband about his affair instead of simply ignoring it, as most women in polite circles did.
President Thomas Jefferson fathered a child by his mistress. So did Warren G. Harding, who also carried on an affair with the wife of a family friend. Gen. Dwight Eisenhower had a long-term relationship with the woman who was his driver in England during World War II. CIA Director Allen Dulles, according to his own sister, had "at least a hundred" affairs, including one with the queen of Greece. President John F. Kennedy's affairs and one-night stands may have numbered even more.
But times have changed. The press and political insiders no longer turn a blind eye. So why do men continue in behaviors that now carry so much risk of exposure and punishment?
