WEDDING-NIGHT SEX

Why it's special
It's the day she's been longing for. She's glowing with pride (and champagne) and looks stunning. "Women are full of the feel-good chemical dopamine on their wedding day," says Dr Pam Spurr, author of Fabulous Foreplay. "That primes her to give as much pleasure as she's experiencing."

Get it every night
"Repeating that wedding-day frisson is all about spiking her dopamine levels," says Spurr.

First, connect back to the happy day. "It may sound cheesy, but playing your wedding song will get those feel-good chemicals flowing," says sex therapist Dr Gloria Brame.

Then, with her reward system triggered, boost the effect through touch. "Gently nuzzle and kiss the nape of her neck," says Spurr. "This helps you bond again over your special day." And this time, you don't have to invite weird Uncle Mick.

YOUR FIRST-TIME SEX

Why it's special
Assuming it wasn't the imminent return of her boyfriend or testing the structural integrity of the boss's desk, that first-time excitement stemmed from novelty. "You're more focused on the task and tune in to all your senses," says Siski Green, author of How to Blow Her Mind in Bed.

It also breaks pleasure-sapping routine. "Many men get sucked into repeating a sexual formula," says Spurr. "When that formula changes - as it does with a new partner - it automatically heightens excitement."

"Mimic that sense of exploration by approaching her body in a new way," says Green. "Physically, try rubbing her with edible massage oil. Or instead of fondling with your hands, use your penis as the point of contact with her erogenous zones." (Just don't try it on a neck rub!)

"Psychologically, you need to get away from the fact that she's your partner, so experiment with role play," Green adds. Different personas can help you explore new scenarios, positions and body parts.

If you can see this idea going down like a bucks night without beer, suggest you take turns coming up with ideas. "This way she won't feel it's a criticism," says Green.

MAKE-UP SEX

Why it's special
You know how this one starts: slammed doors, questioning of parentage, projectile accessories. But as Kofi Annan probably never said, conflict resolution often ends with the perk of a passionate, sense-heightened bedroom summit.

Of course, we're not suggesting you become an antagonistic idiot looking to pick a fight at every available opportunity. But you can both let off some steam and be all the more satisfied for it, mentally and physically.

"Fighting increases levels of testosterone," says Spurr. "This sends your sex drive into overdrive, leaving your mind racing with sexual thoughts and increased stimulation."

Sleeping with her younger, slightly more attractive cousin is always an option, "but you don't actually have to fight to recreate the testosterone boost", says Green. "Watching certain types of films also gets the requisite hormonal juices flowing."

And thankfully there's no need for a shamefaced forage through the rom-coms down at Blockbuster. Researchers at the University of Michigan in the US found violent films or thrillers, such as The Godfather Part II, can increase testosterone levels by 30%. More emotionally in-touch offerings, such as the insipid The Bridges Of Madison County, had the reverse effect.

BREAK-UP SEX

Why it's special
You say tomato, she says tomayto. You say, I'm playing golf, she says you have issues with commitment and all men are bastards. Whatever the reasons, you call the whole thing off. You then experience the cruel irony of your last sex being the best sex.

A study in the US by the University of Arizona found that as a relationship breaks down, altered levels of hormones in men's semen trigger their partners to start ovulating. It's a subconscious trick designed for last-ditch impregnation. But it has a more immediate effect: when she's fertile, her biological drive for sex increases.

Break-up sex can be great. Months of emotional turmoil, junk food and sleeping on your mate's sofa are not. So, you want to get the sex-drive spike without calling on that famous Spanish archer, El Bow.

"To recreate that hormonal boost, use scented candles," says natural therapist Anton Michael Rocke. "Jasmine is renowned for its positive effect on sex drive, which conventional science attributes to hormonal action. Some aromatherapy practitioners also believe it stimulates a secretion of pheromones, making your libido increase." Neither branch of science has yet found a practical use for scatter cushions.

HOLIDAY SEX

Why it's special
Sun, sea, sand and . . . extradition. That was a break to remember. But where there's exposed flesh in spades, there are hormones in buckets. "The change of scenery really does boost mood," says clinical psychologist Dr Victoria Wilson.

And according to Green, "A woman feels extra good about her body on holiday" and will be less inhibited sexually than when she's at home.

Get it every night
You need a change of scene. There's no need to cross time zones, though, just turn off all communication devices and book into a hotel. "By absolving all responsibilities for the day, you'll both unwind," says Wilson.

And keep that credit card out. "Give her a confidence boost by booking her a manicure, facial and fake tan," says Green. This'll leave her feeling more attractive, and studies in The Journal Of Sex Research confirmed that this is linked to increased sexual desire and satisfaction. Synchronise her appointments with the footie and you're laughing.
