Monogamy has become outdated and "polyamorous" relationships, involving multiple partners, could become the new normal, according to a BBC investigation.
A Radio 4 documentary, 'Monogamy and the Rules of Love', which features a pair of wife-swapping couples, who use a Google calendar to plan when they have sex with each other, argues that the "taboo" around sharing lovers between an unlimited number of sexual partners could vanish within 10-years, the Independent reported.
Meanwhile, a Norwegian sex expert with a radical approach to relationships, who predicted that the "power" of monogamy is subsiding, agreed that "multi-partner relationships are coming on the radar" and suggests that they will become common within 30 years, if not ten.
