They are closely followed by the Western Cape and KwaZulu-Natal.
And if you are going to have an affair, it will most likely be in the workplace, says international infidelity service Ashley Madison.
According to their 2019 sign-ups, on a per capita basis, Gauteng is ranked at number one for Ashley Madison’s highest cases of infidelity.
The website’s chief commercial officer, Paul Keable, was in the country last week and told the Sunday Independent that women are taking ownership of their intimate needs and dominating the infidelity service.
Among 50 countries where they operate, South Africa is its 12th biggest market, with a little over 3300 people signing up monthly.
Research done by the University of Missouri Kansas City’s Dr Alicia Walker showed that 80% of women who joined Ashley Madison were in essence living in either sexless or orgasm-less marriages.
There are also more women seeking infidelity than men.
In South Africa there are 1.8 active female accounts for every one active paid male account.
Keable said 70% of their users are looking for traditional affairs and 30% include polyamory, open relationships, swingers and everything in between.
Although dating apps like Tinder and Grindr grew in popularity, Keable maintained that the real competition will always be the workplace.
“That is where affairs happen over the years. You’re looking across from that person spending far more time with them than your spouse.”
In 2015 a data dump worth nearly 10 gigabytes was leaked onto the dark web that included personal information on 32 million users of Ashley Madison.
