Sting and Trudie Styler smooch on night out at Saint Tropez club as they show their marriage is more passionate than ever after years of tantric sex

THEY may be coming up to their 25th wedding anniversary, but Sting and Trudie Styler certainly haven't lost their passion.

The twosome shared a smooch in a Saint Tropez nightclub yesterday with Trudie wrapping her arms around the rocker's neck.

Wearing a green strappy dress with spaghetti straps, the slim 63-year-old wrapped her arms around Sting who looked more than happy with the snog.

The couple married in August 1992, and went on to have four children together.

Sting once famously divulged the secrets of their happy union by revealing the couple indulged in "eight hours" of  tantric sex.

He's since said the comments were a joke and tried to clarify them on a US talk show.

He told Inside The Actor's Studio: 'The idea of tantric sex is a spiritual act.

"I don't know any purer and better way of expressing a love for another individual than sharing that wonderful, I call it, 'sacrament.' I would stand by it. Not seven hours, but the idea."

Bedroom antics aside, Sting says the secret to their long lasting relationship is simple friendship.

He told Harper's Bazar: "Relationships aren’t easy, and I don’t think they’re particularly natural, but we’re lucky because we actually like each other.
"We love each other – that’s a given – but Trudie lights up my world when she comes into a room.

"I don’t take her for granted.’
