"Fifty Shades of Grey" has been spicing up sex lives, according to reports, and women are demanding new techniques in the bedroom.

"Fifty Shades of Grey," written by bestselling author E.L. James, tells the story of 22-year-old recent college grad Anastasia Steele, who enters into a dominant/submissive sexual relationship with a BDSM-crazed billionaire named Christian Grey.

"Fifty Shades" is not the only erotica to blow up this summer.

"Bared to You" by Sylvia Day has become a popular romance book, and has been on the New York Times Bestsellers list for weeks. The books is currently #4 on the Paperback Trade Fiction list.

According to Marie Claire, "Bared to You" is tipped to be the next big thing, having sold 50,000 copies in Britain in its first week.

The 39-year-old author did a recent interview with Marie Claire on how sex has become big this summer.

"I will confess - I smile at those who are surprised that women enjoy reading erotic fiction. It's a secret and knowing smile. Why? Because I've been writing erotic romance for nearly a decade," Day said.

"Women have been reading sexy stories for many years, in large enough numbers to ensure that it's the rare week when an erotic title isn't on the bestsellers lists in the US. But the media didn't know that."

"There's nothing new or unexpected about women reading erotic stories - we've been doing it for ages. But we're busy; our precious time is spent juggling work and households. As with anything, make it convenient to buy what we want and we'll take you up on it. It's just that simple."

This new phenomenon has made some women want to spice things up in bed with their partners.

According to the Huffington Post, men are feeling pressure as they struggle to keep up with all the kinky demands from their "Christian Grey-loving partners, a study has found."

A survey by ECigaretteDirect.co.uk found more than half of the 500 men they quizzed (55%) admitted they felt more under pressure than ever to step it up in the bedroom after their partner read the erotic novel.

"I'd heard a little about the books and thought it would be a good idea for my wife to give them a read - I didn't know what I was letting myself in for," one participant said, according to the study.

"I don't know whether I'm going to be able to meet her demands and keep her satisfied."

The 'Big British Sex Survey' by Durex discovered that nearly one in four Brits participate in bondage.

A further 38% admitted to using handcuff during sex and 41% enjoy being spanked. Nearly one in 10 (8%) use a butt plug during sex - another taboo broken in the BSDM (Bondage and Discipline, Sadism and Masochism) world of Fifty Shades.

"Most men like to believe themselves to be sexually driven alpha males but when it's the female dictating the lovemaking it seems for many this can come with significant added pressures," a spokesperson from ECigaretteDirect told HuffPost Lifestyle.

"The poll offers some really interesting insight into the male psyche and I think dispels the myth that they are all sex mad.

"Instead what we have found is that they can often be all mouth and no trousers, preferring to boast about their sexual exploits rather than live up to them when given the opportunity."

OpposingViews.com said that there's nothing wrong with BDSM, and there is nothing harmful about it, contrary to what some people think.

"Whether it's psychological or physical restraint, giving up power can be very liberating, especially when you trust your partner to take you both where you want to go," article read.

"BDSM is about a power exchange and the end goal is trust. Giving someone else the gift of our emotional vulnerability can enhance our sexual confidence and strengthens our psychological core. For many women, there's nothing more empowering. It's that message that underlies well-written erotic romance, and is enticing women to explore it further - even if it's only in the pages of a book. In healthy, loving BDSM practice, relinquishing control can actually set a woman free."

While "Fifty Shades of Grey" opens communication for some couples about what they want out of sex, speaking up can be hard to do.

"It's become generally accepted that communication is the key to good sex - communication tips have become a cornerstone of sex guides for everyone from Christian couples to sex slaves. But talking can be difficult, and maybe the popularity of 50 Shades is in part a backlash against the admonishment to talk, a sign that sometimes people yearn for someone who just knows," wrote Anna North on Buzz Feed.

North quoted Carl, a truck driver from Washington, saying that men "don't know what to do" to please woman sexually and that they have to speak up.

"50 Shades of Grey is a fantasy, and real people usually aren't as naturally in sync as Christian and Ana."

Carl suggested that women print out sections and hand them to their partners so they know what to do.

"And while this may not be for everyone, for some women, 50 Shades could take some of the pressure out of communication. Maybe the book can do the talking for them," the writer implied.

So "Fifty Shades of Grey" fans, what do you think about how the book has changed some sex lives, and the pressure men feel to meet their partners' demands? How do you feel about how the book portrays BDSM?
