'If you are not prepared to put the work in and take the rough with the smooth, you are going to struggle to find that ideal.

'Everyone wants to have a perfect marriage and it seems that the little things such as kissing and cuddling really are important.

'While they might seem insignificant, it's the little gestures which can help couples retain their closeness and intimacy.

'If you lose this, that's when your marriage can become stuck in a rut and lead to two unhappy or bored people.'

The study, carried out between January 30th and February 9th, polled Americans from across the country.

It found the perfect marriage will also see couples have sex three times a week, and enjoy around seven cuddles during that time.

Six nights spent cuddled up in front of the TV and two nights out with their own friends each month, along with two mini-vacations a year also make a successful marriage.

Even having three arguments a month was among the list of secrets.

It also emerged that more than half were friends before they actually became a couple, and waited an average of just over three years before walking down the aisle.

The study also found that Americans consider the biggest secret of a happy marriage to be simply accepting each other's faults.

Trust, honesty, respect and just supporting each other also featured in the top five.

Other 'secrets' to a perfect marriage include being kind to each other, compromising and also knowing when to give your partner some space.
