The poll of 3,000 adults discovered that two fifths of cheats ended up kissing someone while out clubbing while almost one in four cheated with a colleague at a work event.
Fifty five per cent of the ladies confessed that they loved attention from men - and more than a third said men often get the wrong idea because they were so flirtatious.
More than a third also claim their 'minor indiscretion' happened by accident because their flirting got out of hand.
The study was conducted by Opera North to open their new season with the Mozart opera Cosi fan tutte, translated as 'All Women Are Like That' - a light-hearted comedy that looks at the very nature of infidelity, reports The Daily Express.
More than one in 10 women say they will never be completely monogamous in a relationship because life is too short.
A fifth of women admit they get a thrill from cheating on their partner, and despite knowing it is wrong want to do it again.
The poll also showed one in four women find complete strangers attractive and love the thrill of chasing them on a night out.
A further one in four said they could not resist the temptation of a man in uniform.
