When married couples were asked what advice they would give to newlyweds, we half expected them to cynically say "enjoy the honeymoon sex while it lasts."
But it turns out most couples do not think getting hot and steamy in the bedroom is the key to a happy marriage. Instead, they rate honest conversation above all else.
A study of 2,000 men and women who have been married for 10 years or more revealed the most common advice they'd give newlyweds is to talk to each other.
Only 1% of those surveyed said a good sex life was important in a successful marriage, leaving hanky panky way down in 18th place.
Perhaps unsurprisingly, "keep going", "work at it" and "don’t give up on the marriage too easily" were all in the top five choices, showing marriage isn't a walk in the park for many.
At number 13 was the cutting "don't get married" - ouch.
Sarah Thompson, a lawyer for Slater & Gordon who commissioned the study, told the MailOnline: "What's clear from my work as a family lawyer is that marriage can be hard work.
"Sadly, despite the best intentions in the world, not every marriage will last forever.
"As this research has shown, communication and compromise can be the key to a happy marriage, but they are also the attributes that can help resolve a relationship that is over in the best possible way for all parties involved."
