Experts reveal why men cheat at Christmas parties even if they are married
MEN lose interest in relationships when they feel frisky, such as at a Christmas party, a study found.
Getting sexually aroused switches their focus to so-called short-term mating — even if they are married.
Meanwhile, their long-term mating motives plummet.
It means they are more likely to want a fling or one-night stand rather than a lasting relationship, according to researcher Dr Arnaud Wisman of the University of Kent.
He added: “It did not matter if men were in a long-term relationship or not — sexual arousal still increased the desire for a fling.”
His study involving 102 straight men was published in the journal Evolutionary Psychological Science.
Half were given erotic images, while the others were shown tropical birds or sports.
More than half of those who viewed sexual material said they would prefer a quickie over a relationship.
The figure dropped to below four in ten for those shown neutral images.
It may go back to prehistory when men jumped at any chance to breed to carry on their bloodline, the researchers said.
