It might be slated by critics from all corners of the globe, but blockbuster sales of the mummy porn novel Fifty Shades of Grey suggest that there are quite a few fans out there. And if a recent online survey in Britain is to be believed, women are getting wilder and more active in the bedroom thanks to the book.

Women reported a drastic leap in the regularity of their sex life after reading the book - from once a week to three times a week, according the survey of 2183 on Netmums.com.

This time last year, it was just three percent of women who said they had sex every day, but the results showed that this is up to one in eight women after the launch of Fifty Shades of Grey.

Not only are women engaging in sex more frequently, they're also enjoying sessions that last 15-minutes longer.

Better still, the book has inspired 64 percent of women to be more adventurous during their lovemaking, trying out new sex positions and sex toys, while 54 percent said that their increased in lovemaking had improved their emotional closeness with their partner.

Those who choose to visit sex shops are buying blindfolds, handcuffs and vibrators, while a braver few are trying out bondage ties, sex balls, whips and paddles.

Women have dropped doggy style as their favourite sex position and instead, vote "reverse cowgirl" - in which the woman mounts her man backwards - as their top position.    

Naturally, almost half of women reported that their men were delighted that they had read the book. A surprising 11 percent had been banned from reading the book by their partner because they considered it "disgusting."

"It’s not called Mummy Porn for nothing," said Siobhan Freegard, founder of Netmums.

"It's a phenomenon which has put a smile on millions of women’s faces - and the twinkle back in their partner's eyes.

"But it's also interesting to see how reading the book and spicing up your sex life can make you emotionally closer to your partner. Here's hoping the 50 Shades effect will see couples grow stronger together and well as having more fun in the sack."
