Why its monumental: It's her perfect day. She looks gorgeous (and she's been told that 493 times an hour). Her whole family is around her. And now she truly feels the comfort and security of having a husband. Translation: "The reward system in her brain is going bonkers," says anthropologist Dr Helen Fisher.

Physiologically, her feel-good chemicals - dopamine and epinephrine - are firing fast, meaning she's wired to feel euphoric and to give as much pleasure as she's receiving.

Even if you went on your honeymoon 12 years ago, or don't plan on going on one for another 12 years, you can create the spark by triggering her reward system. Try these tricks: In the morning, use a ballpoint pen to write a sexy note somewhere on her body. Try the top of her thigh (prime real estate, with minimum exposure to co-workers). "Women are turned on by words," Fisher says. Start with 'I', end with 'you', and use the verb of your choice in between.

Giving her nine or 10 hours to see, think about and fantasise about your note starts the percolation process. When she comes home, try this move. While facing her, hold her head with both of your hands, tilt her head back and gently kiss the side of her neck. "If you touch a woman the way she wants to be touched, she'll be all over you," says Paget. That means staying away from your traditional 'go to' spots and kissing the parts of her body you usually ignore, like the back of her hand, the tops of her feet, the inside of her elbow or her hipbone.

Now that you're under the covers, expand your repertoire of oral sex - a nice reward in itself. Paget suggests the Kivin method: you lie perpendicular to her body, which allows you to stroke her clitoris with your tongue in a cross-wise motion, rather than up and down. She'll appreciate the change in stimulation - hopefully, enough to return the reward.
