CapeTalk/702's Eusebius Mckaiser and Sexologist Dr Eve look at how the idea of morality around cheating has changed over time.
Dr Eve says that between 25 and 70 per cent of women, and 40 - 80 per cent of men have engaged in at least one extramarital sexual encounter.
But we cannot really rely on these figures because not so many people will admit to doing something that is considered as morally harmful, she says.
At the moment there are still no clear statistics on cyber infidelity.
The sands of morality around infidelity have shifted enormously, says Dr Eve.
The traditional view point tends to be that no one really admits to infidelity and certainly would not tolerate it. But now there is the growing phenomenon of cyber infidelity, which was not there before the emergence of new technology. This may be changing the way we morally view infidelity. It may be shifting our set of values around what it means to cheat in a relationship.
Dr Eve believes that society needs to catch up with the behaviour happening on the ground.
The morality of what once was taken for granted as cheating in real life has shifted so much that we don't know what our morals around infidelity are anymore— Dr Eve, clinical sexologist
Dr Eve explains cyber infidelity as two people who are at the same time online, they are both in significant relationships... they are keeping it a secret and also know that if their partners were to know what they are doing, their partners will define it as cheating.
