According to the poll, one in five Britons believe that sharing the bed with an ex while dating a new girlfriend ‘doesn't really count’.

In fact, in the 'Why Men and Women Cheat' survey, more than 50 per cent of all blokes have claimed that they prefer two-timing, even if they were in a happy marriage or relationship.

"Many men who love their partners and have great sex at home never turn down an opportunity for a bit on the side if they think they can get away with it," the Daily Star quoted pollsters in the survey as saying.

In the survey, only a third of female love cheats said they were happy at home, blaming boredom as the main reason they slept around. And they claimed having an affair was a much-needed ego-boost.
