A new research has pointed out that when it comes to a long-term relationship, such as marriage, men look at faces of women rather than bodies.
The results of study support the belief that men are instinctively attracted to women's bodies if they are keen on a "no strings" sexual relationship.
But a man pays more attention to a woman's face if he is thinking of settling down and starting a family.
Academics at the University of Texas claim that this is because a woman's face provides strong clues to her "reproductive value," reports the Daily Express.
The study looked at the reactions of 375 men and women who were asked to consider dating a member of the opposite sex whose face or body had been obscured.
Women proved consistent, opting for facial features whether they were interested in having a fling or finding an ideal husband.
But the male volunteers went for sensual bodies in what was termed 'the short-term mating condition', and faces in 'the long-term mating condition'.
The study was published in science journal 'Evolution And Human Behaviour'.
