Traditionally having an affair was a big taboo but with the rise of extra-marital dating sites and a more open-minded attitude towards sex in general that may no longer be the case.
Webite The Richest crunched data from hookup sites and Durex condoms to reveal the nationalities most likely to cheat.
But it seams having a steamy affair is not always as taboo as might be expected and the list shows the countries which are most often cited as having illicit affairs.
The liaisons are called ‘parallel relationships’ and society is relatively open-minded when it comes to having a bit on the side.
A survey by Match.com found one in five married men had had affairs with at least ten women – seven times the rate among women.
United Kingdom 36%
The British aren’t traditionally known for their fiery sex lives with other more passionate countries mocking our cooler national
But that may have changed.
In fact the owner of a leading website, Ashley Madison, which helps arrange extramarrital affairs claims at least 1 million Brits are interested in cheating on their partners.
It’s probably little comfort for concerned partners that Britons who cheat are far more likely to feel guilty than their European counterparts.
The southern European country is associated with having a passionate and fiery temperament so it is perhaps surprising that Spain does not feature higher up the list.
However, while the influence of Spain’s Catholic Church is waning, it seems to still hold some sway since extra-marrital affairs remain somewhat taboo in the country.
According to magazine New Europe, Belgian married dating website Gleeden boasts 1.1million members, with advisor Chantal Bauwens saying cheating is no longer taboo in the country.
She said: ‘It is no longer a “wrong” that allows the injured party to request separating due to the wrongs of the infidel,’ she says. ‘Is your spouse cheating on you? Yeah, so? Do the same or divorce!’
According to dating website Victoria Milan which caters for married men and women looking to play away, Norwegians are less likely to use the site during the cold winter months.
But when the mercury rises it seems that so does Norwegians promiscuity.
The Gallic people have always been thought of as fairly open-minded when it comes to matters of the heart.
In fact the traditional l’heure bleue refers to the hour after work when men would go and visit their mistress.
France is the only country in which most people believe affairs are morally acceptable and only 28 per cent of adulterers said they regretted their affairs.
When President Hollande was accused of nipping off on a scooter in the middle of the night to see his mistress his poll ratings, rather than take a nosedive, actually went up.
It might come as a surprise that the Germans are more likely than the French to have affairs.
But it seems the French have some frisky neighbours who are perhaps just more discreet about playing away from home.
The country that gave us the original ladies man Giacomo Casanova famed for bedding hundreds of women lays a strong claim to third place in the world ranking.
Italy also elected Silvio Berlusconi known as much for his Bunga Bunga parties as for his politics.
But it doesn’t seem like the Italian’s adultery is harming marital relations.
Although it has risen in recent years the country still has one of the lowest rates of divorce of any nation.
The Scandinavian country always scores highly on ratings which judge the happiness of its citizens, but it seems they also score highly when it comes to adultery.
Although it seems that the activities of those living in the capital Copenhagen maybe pushing up the average rate.
More than one-third of people residing in Copenhagen have been unfaithful to their partners.
Despite that almost half those who are married admit having an affair.
But it’s Thailand which grabbed the top spot with 56% of the population admitting to being unfaithful.
Thailand has a whole host of being unfaithful including the traditional mia noi (minor wife).
The younger generation also enjoys the casual kik culture where men and women have extra friends they spend time with aside from their partners. Not all of these relationships are sexual.
There has also been a growing sex-for-sale culture which is mainly aimed at men in massage parlours, clubs and brothels.
But in 2012 when a Durex survey suggested women were more adulterous than men they faced a backlash from the Thai media.
Of course just because a country doesn’t feature in the top ten it doesn’t mean there aren’t plenty of men and women sneaking around there.
After footage of two office workers caught in a steamy encounter in New Zealand went viral it’s perhaps surprising the southern hemisphere country didn’t make the top ten.
Obviously no one really knows the exact truth!
