On Tuesday 20th November 5 Live is hosting the #sextakeover - a day of programming focussed on sexual behaviour, relationships and attitudes in the UK.

Ahead of the event we spoke to husband and wife Thomas and Cathy Keen, and their partner Nicole Everett.

They are in a three-way relationship and identify as a ‘throuple’.

"As soon as you say a three-way relationship, people automatically think this must be about sex. When in reality this is something like as genuine and as significant as a couple relationship," said Cathy.

"The third person is the mediator. So they can see it from an outside perspective of whatever that situation," added Nicole.

They talk openly about how they became a throuple, parenting Thomas and Cathy's son and their sleeping arrangements.
