Having an affair with a friend's missus or girlfriend seems to be common practice.
A survey by a British internet dating company has found nearly half of the 5,000 unfaithful men it polled admitted to affairs with a friend's partner.
A staggering 46.9 percent said they had a fling with a mate's wife or girlfriend.
The survey was conducted amid the frenzy of reports about former England soccer captain John Terry – who allegedly had an affair with the former girlfriend of England team mate Wayne Bridge.
