Gemma, 43, and Daz, 40, have been swingers for five years. They say it not only saved their relationship, but also strengthened their relationship.

Gemma says they often get to know the other swingers before they all go to bed together. They hope to break down stigmas about swingers and encourage other couples to try the lifestyle, but they say communication is key. "Be clear between yourself and your partner exactly what you want to get out of it," said Gemma.
