David Beckham would consider getting a tattoo on his penis.

The soccer star estimated he has around "30 or 31" pieces of body art and plans to have further inkings in the future - and wouldn't rule out having one in an intimate area.

TV talk show host Craig Ferguson asked: "Did you get any on your business?"

To which David replied: "Not yet. I was thinking about it just then."

What Craig jokingly suggested they could "go together" to get tattoos on their penises, the British hunk agreed, saying "sounds great" but admitted he would need to think of a design first.

If David, 36, does go ahead with the intimate inking, his wife Victoria -- who is pregnant with their fourth child -- is not likely to be pleased.

He said: "Every time I have a tattoo she's like, 'Not another one.' "

David also said he'd let his boys -- Brooklyn, 12, Romeo, eight, and six-year-old Cruz -- get tattoos when they are old enough -- but not his daughter, due to be born in six weeks.

He added: "I'm not sure I would let her get tattoos but the boys I couldn't really argue with. I love mine personally, but I'm not sure they're going to look great when I'm 75."

The sportsman also told how it was "amazing" to meet U.S. president Barack Obama at a dinner in London during his visit last week, and that he was shocked when at the same event, Queen Elizabeth asked him about his personal life.

David -- who was a guest at Prince William's recent nuptials to the Duchess of Cambridge -- said: "Funnily enough she knew I was having a baby in six weeks. It shocked me that she knew. I love the queen."
