More than half of all married Brit men have had no-strings attached sex, reveals a shocking new survey by NetDoctor.
And thanks to websites such as MaritalAffair.co.uk and IllicitEncounters.com, it is easier than ever to arrange extra-curricular activity in secret.
The survey found that thousands of cheating spouses have signed up in search of no-strings extra-marital sex, reports the Sun.
To reveal the dirty world of husbands, the Sun reporter Laura Stott went undercover to meet real Internet love rats and to expose the lies they tell their unsuspecting wives.
The survey revealed that some men were looking for affairs online because they felt trapped in their marriages.
In one of the most shocking case, the survey found that a man was looking for no-strings attached sex just because his wife had cancer and had lost her sex drive.
Some men oddly enjoyed the thrill of having sex with other married women while their wives enjoy family weekend, the study found.
