These Eight Things Could Be Killing Your Sex Life

GOING ON A DIET

If you're trying to slim down, it could have an unwanted side-effect.
Losing weight too quickly puts stress on the body - even if you are a healthy weight - which can trigger the release of a hormone called prolactin, a powerful suppressor of sex drive.

Losing more than 10 per cent of your weight too quickly can make the body think it's starving, which can cause sexual interest to fall, she adds.

HAVING A DESK JOB

A sedentary job is just as bad for a woman's potential to orgasm, warns Dr Fromberg.
"If you sit with rounded shoulders and your tail tucked under for hours, the muscles of your pelvic floor and the psoas muscle (which runs diagonally from the lower back through to the groin) remain chronically at 'half mast' - not stretched or contracted," she says.

This can affect the signals passing along important nerves leading to the reproductive organs. 

The body is designed to move constantly, so the more active you are, the more effectively blood supply and nerve signalling can work.

SLIPPING ON A PAIR OF HEELS

They may look sexy, but high heels could make sex less enjoyable for some women.
Dr Eden Fromberg, a New York-based gynaecologist, says that because heeled shoes tip the body forwards, this forces the postural muscles to contract as the body works to maintain an upright posture.

"If the pelvic floor muscles are chronically contracted, they can become tight and therefore restrict the passage of nerve impulses going through them to the reproductive organs and arousal tissue," she says.

"Wearing high heels all day can affect a woman's orgasm - there is a reported improvement in female patients who retire their heels or use them only rarely."

BEING HOOKED ON REALITY TV

People who have a TV in their bedroom have sex half as often as those who don't, according to a 2006 study of 523 Italian couples.

The effect is more marked for the over-50s, with the average of seven couplings a month falling to just 1.5 on average.

According to Dr Edwards, good sexual relations depend on couples communicating with each other, not sitting side by side watching television.

"If whatever you are watching makes you sad or grumpy, it is more likely to affect your libido," he says.

Technology can affect your love life in other ways, too. Sitting and spending more than seven hours a day on an electronic gadget (such as a phone or tablet) can trigger back pain, according to the British Chiropractic Association, and a recent survey of 2,000 people by backpainhelp.com found that 25 per cent had avoided sex because of back pain.

YOUR "CUDDLY" LOVE HANDLES

As well as triggering energy slumps, excess sugar in the diet is laid down as fat, which can raise oestrogen levels, reducing the effect of testosterone in women and men.

"The more body fat you have, the more chance the testosterone in your system will be bound into the fat, which means less 'free testosterone'," says Dr Edwards. "Not only will this reduce libido, it makes you more likely to gather fat in your abdomen, which binds to any remaining testosterone, so diminishing your available supply."

YOUR FEET ARE JUST TOO COLD

Women need warm feet for orgasm, suggested a Dutch study published in 2005.
Researchers revealed that 80 per cent of women were able to achieve orgasm when they wore socks, compared with 50 per cent when barefoot.

According to Professor Gert Holstege, a neuroscientist at the University of Groningen who led the study: "The feet play a significant role in maintaining body temperature, and by regulating internal climate the mind and body can come into a relaxed state needed for an orgasmic release."

A POOR SENSE OF SMELL

Smell plays an important role in our recognition of pheromones - the scents given off by a partner's body through sweat - and affects sexual behaviour.

A 2012 study at the University of Gothenburg in Sweden found that men with no sense of smell had significantly fewer sexual partners than those with a normal nasal function, and women with no sense of smell felt less secure in their relationships.

Psychologist Dr Ilona Croy, who led the study, says having impaired smell will give you a disadvantage in the mating game.

"A lot of social signals are transported through the olfactory channel (the nose lining and associated nerves) and a depleted sense of smell makes it likely that you might miss them," she says.

THAT WEEKEND BIKE RIDE

Men who exercise regularly have a 70 per cent reduced risk of erectile dysfunction compared with men who do none - but serious cyclists are more likely to suffer impotence.

It seems the firm, angular saddles can put pressure on nerves and arteries around the groin, reducing blood flow to the penis.

"If there is bruising to the pudendal nerve (a major nerve in the groin that runs from the genitals to the base of the spine), erectile dysfunction can last for up to two years," says Dr Edwards.

But it's more typically seen on Mondays or Tuesdays after a weekend in the saddle, he adds.
