Matthew and Michelle Catano from Huntington Beach, California, met a decade ago but after years of marriage decided something was missing.
They used a dating app two years ago to hook up with 26-year-old Courtney who has boosted their sex life with threesomes as well as their family bond.
Two years later, they are living as a polygamous triad and meet up with other like-minded lovers calling themselves poly families.
Despite having been married for 10 years, there is no jealousy when it comes to the trio’s sex life.
Matthew told The Sun: ‘Being involved with two women is a confidence booster. I’m a needy person so enjoy the extra love and affection.’
As well as spicing up his life in the bedroom, the unorthodox arrangement has given him an extra pair of hands on deck around the house with chores and childcare.
The new addition to the relationship is a stay-at-home mom, meaning the kids get more support and allow Michael and Michelle to work full-time.
All three share their love for each other on social media.
‘I love you Michelle. Always my women’s crush.’
And not wanting to leave anybody out, after just six months together Courtney posted a picture of the entire gang with the caption: ‘I don’t normally do this but I fell head over heels for these people.
‘I love you both and the kids so much thank you for coming into my life.’
Like any other family, they go on holidays and meet other people with the same interests as themselves.
In April, they met Buddy, Rose and Lauren Sully – a polygamous trio with children just like them.
Upon meeting, the Sullys posted a photo and a caption reading: ‘We got to meet our first triad/poly family today.
‘Can’t wait to get our families together again.’
They are two of a growing number of similar families in the US openly living as a three as opposed to the conventional two.
