According to a new survey by online dating website Smooch.com, men are a third more likely to be unfaithful than women.
It reveals that 41 per cent of guys have cheated on a partner at some point, compared to 29 per cent of girls.
The survey also shows that the older a man is, the more likely he is to stray, with 44 per cent those over 60 admitting to infidelity, compared to 31 per cent of those aged 18 to 24.
