We're used to thinking men are more likely than women to stray in a relationship -- but it seems the roles are being reversed.
A new survey suggests that it's women who are more unfaithful, with four in 10 admitting that they have cheated on their partner.
By comparison, three in 10 men said they had done the dirty on their nearest and dearest.
It also emerged that four in 10 cheats ended up snogging someone whilst out clubbing, while almost one in four got carried away with a colleague at a work do.
More than half of women said they loved attention from men. More than a third said men often got the wrong idea because they were so flirtatious.
More than a third of women also claimed their "minor indiscretion" happened by accident because their flirting got out of hand.
According to sex and relationships expert Alex Hooper-Hodson, the survey results reflect current trends.
He said: "There has been a massive change in this issue compared with previous years.
"In the 80s, an academic called Annette Lawson wrote a book called "Adultery" in which she said the rate of infidelity among men was 60 percent over the course of a marriage and 40 percent for women.
"But the book also showed that the rate of increase in infidelity was higher among women, so it was likely they would overtake men.
"What you're seeing now is the result of that trend. "It could be put down to women being more fussy, more picky, more confident and more in charge of their lives than they were 20 years ago. "In a sense, they're behaving like old-fashioned men. They're having their cake and eating it." The research showed that 58 percent of women who have cheated have kissed someone other than their partner, while 27 percent have had sex with someone else. And 47 percent admitted they cannot help dancing provocatively with men whenever they are on a night out. A fifth of girls said they get a thrill from cheating on their partner and, despite knowing it is wrong, want to do it again. The survey also revealed 27 percent of women find strangers attractive and love the thrill of chasing them on a night out. One in four said they cannot resist the temptation of a man in uniform, while almost one in five tend to cheat with those in authority. Builders and gym instructors are common targets for women, as one in 10 said they cannot help flirting outrageously with them. Suzy Miller, creator of Britain's first ever divorce fairs, feels the figures could simply point to women being more honest. She said: "I think these days there is less social stigma attached to infidelity and people regard it as more normal, which is not a good thing.
"In places such as France and Italy, the culture is much more relaxed about these things, so perhaps our attitudes are becoming more continental. I think women are also more willing to give reasons for their infidelity, such as being unhappy. "I can imagine there being a lot of women out there in long-term relationships who feel neglected, while their partners become complacent. But Suzy did admit that more women in relationships are indulging in "minor indiscretions" in places such as parties and nights out. She said: "A lot of that goes on as people are drinking so much alcohol and doing so much going out and partying. The idea that you only do that when you're young isn't true at all. Nowadays, we keep going for as long as we possibly can. "But I'd be surprised if there are actually greater levels of infidelity now than there were in the past. "I think it's just that people are more able to talk about it and there is less stigma attached to it. "At least if we're more able to talk about these things, we're more likely to look at what's going wrong." Hooper-Hodson agrees that our changing social lives could be contributing to the problem. He said: "Society has changed to some degree and it's changed women's outlooks.
"It's almost an extension of the lad culture. Women are effectively taking up that male role, while men are becoming a bit more sensitive. "The drinking and clubbing culture has increased massively over the last 30 years and it's a whole different ball game in terms of going out and having fun. "That's certainly the case with younger people but you also have to look at people in their 30s, 40s and 50s who are being unfaithful. "Even though people know they're doing something they shouldn't, they want to have a bit of excitement and drama in their lives."
