IT’s not widely known... but the women of Oxfordshire are among the nation’s naughtiest.

According to a new survey 73 per cent those in the region have tried everything from bondage to threesomes – more than anywhere else in the country and five per cent above the national average.

The revelations come courtesy of erotic romance publisher Totally Bound, which found UK women were adventurous in bed (and other places) but generally preferred not to talk about their sexy exploits with others (apart, it seems, from in the survey!).

It showed that 68 per cent of British women experiment with sex but over three-quarters of them kept it a secret.

A surprising 67 per cent said they wouldn’t even talk to their partner about sex The survey – Britain’s Secret Sex Lives – questioned 2,000 women to explore how their real lives compared to their fantasies.

Nearly half (45 per cent) admitted that they thought about sex more than they actually had it, and the ultimate fantasies were revealed as dominance and submission role plays (25 per cent) or involving a fireman. A beach came top as ideal fantasy location (34 per cent).

Younger women were shown to be the most daring in the bedroom, whilst women over 55 the most conservative and least likely to be open about sex.

“These findings suggest that despite the Fifty Shades phenomenon, as well as the surge in explicit television shows such as Channel 4’s Sex Box, which films couples having sex and then discussing it afterwards, UK women still prefer to cultivate an air of mystery around their real and fantasy sex lives,” said a spokeswoman for Totally Bound.

The survey was commissioned to mark the publisher’s What’s Her Secret? series, to be released later this month.

“We’ve conducted extensive research to thoroughly understand what UK women want when it comes to real and imagined sex,” said Claire Siemaszkiewicz, CEO and founder of Totally Bound. “We want to inspire women to fulfil their rich and varied fantasy lives.”

The What’s Her Secret? box set of six eBook short stories will be available on November 29 from totallybound.com priced £2.50 for the first week and then £5.
