Carnal Knowledge

Carnal Knowledge is a 1971 American comedy-drama film directed by Mike Nichols and written by Jules Feiffer.

A synopsis of the film which appeared in the Saturday Review by Hollis Alpert was later quoted in a legal proceeding as follows:

of two young college men, roommates and lifelong friends forever preoccupied with their sex lives. Both are first met as virgins. Nicholson is the more knowledgeable and attractive of the two; speaking colloquially, he is a burgeoning bastard. Art Garfunkel is his friend, the nice but troubled guy straight out of those early Feiffer cartoons, but real. He falls in love with the lovely Susan (Candice Bergen) and unknowingly shares her with his college buddy. As the "safer" one of the two, he is selected by Susan for marriage. The time changes. Both men are in their thirties, pursuing successful careers in New York. Nicholson has been running through an average of a dozen women a year but has never managed to meet the right one, the one with the full bosom, the good legs, the properly rounded bottom. More than that, each and every one is a threat to his malehood and peace of mind, until at last, in a bar, he finds Ann-Margret, an aging bachelor girl with striking cleavage and, quite obviously, something of a past. "Why don't we shack up?" she suggests. They do and a horrendous relationship ensues, complicated mainly by her obsessive desire to marry. Meanwhile, what of Garfunkel? The sparks have gone out of his marriage, the sex has lost its savor, and Garfunkel tries once more. And later, even more foolishly, again.
