The ex-England captain opened up about his longlasting marriage to the fashion designer and former pop star in a wide-ranging interview on the 75th anniversary edition of Desert Island Discs.
He said keeping an open dialogue was the secret to their “strong family unit”.
Beckham, 41, said: “We all know marriage is difficult at times and it’s about working through it.
“We know each other better than anyone knows us.
“We’ve got strong parents, we were brought up with the right values. Of course you make mistake over the years. Whenever we’ve come through tough times ... we talk.”
He added: “People have talked about ‘do we stay together because it’s a brand?’ Of course not, we stay together because we love each other, we stay together because we have four amazing children.
“We’re very respectful of our life. And when we do go through tough times we work through them as a family, as a unit.”
He said that when the couple first started dating they spend their dates in his “amazing bright blue” BMW in order to keep the relationship private.
“I drove down, I picked her up ... we used to sit in a Harvester car park and we just used to kiss, of course, and spend time together.”
The couple married in an extravagant ceremony in 1999, with Beckham cringing as presenter Kirsty Young recalled the lavish affair which saw the happy couple wearing purple outfits.
“That was bold,” said Beckham. “What was I thinking?”
The ex-professional footballer, who signed for Manchester United when he was just 16 and was part of the Class of ‘92 alongside Ryan Giggs and Paul Scholes, did not pick a single record from his wife’s Spice Girls discography.
He revealed he keeps all his England caps at his house and his “precious” medals in a safe in a bank.
“I have so many pairs of boots, over a thousand pairs of boots. I keep them in storage.”
Asked by Young if it competes with Victoria’s shoe collection he replied: “It does actually.”
Speaking about the current child sex abuse scandal in football, Beckham said: “There was never anything at Manchester United and it is disgraceful what has gone on and there has to be something done about it.
“The closest part would have been certain professionals that if we had gone out of line they would have made us do a funny dance in the middle of the changing room in front of the professionals, in front of our heroes at the time.”
