A married couple who encourage each other to sleep with others has visited more than 20 countries for their 'sexploits'.
Cate Wander, 37, and her husband, Darren, 47, a salesman, met 15 years ago in Sydney, Australia and initially started dating as a monogamous couple.
Five years into the relationship, the pair decided to open up about their different desires, ranging from career aspirations to sexual fantasies.
