LONDON, Oct 31: Researchers are struggling to understand a rare medical condition where sufferers unknowingly demand, or actually have, sex while asleep, New Scientist magazine reported.

Research into sexsomania -- making sexual advances toward another person while asleep -- has been hampered as sufferers are so embarrassed by the problem they tend not to own up to it, while doctors do not ask about it.

As yet there is no cure for the condition, which often leads to difficulties in relationships. "It really bothers me that I can't control it," Lisa Mahoney told the magazine. "It scares me because I don't think it has anything to do with the partner. I don't want this foolish condition to hurt us in the long run."

Most researchers view sexsomnia as a variant of sleepwalking, where sufferers are stuck between sleep and wakefulness, though sexsomniacs tend to stay in bed rather than get up and walk about.

While sleepwalking affects two to four percent of adults, sexsomnia is not thought to be as common a problem, according to Nik Trajanovic, a researcher at the sleep and alertness clinic at Canada's Toronto Western Hospital.

But an Internet survey of sexsomniacs carried out in 2005 that drew 219 reliable respondents concluded it was more prevalent than medical case reports alone might suggest.

"Most of the time sleep sex occurs between people who are already partners," Mark Pressman, a sleep specialist at Lankenan Hospital in Wynnewood, Pennsylvania, told the New Scientist.

"Sometimes they hate it," added Pressman of the reactions of sexsomniacs' partners. "Sometimes they tolerate it. On rare occasions you have stories of people liking it better than waking sex."

With no cure, addressing triggering factors -- stress or sleep deprivation -- can help, while Michael Mangan, a psychologist at the University of New Hampshire in the U.S. has set up a Web site, www.sleepsex.org, to help sufferers.

Meanwhile Trajanovic is devising a procedure for diagnosing sexsomnia in legal cases where sufferers have been accused of sexual assault.

Hefner playing dominoes with bunnies

LONDON, Oct 13: At 80, it seems Playboy millionaire Hugh Hefner has no energy left for `bonking` and `holding hedonistic bunny-girl parties` at his mansion, something he is famed for. The aging entrepreneur has confessed that though he`s biologically fit, he is now bored of bedding babes, and would rather like to play `dominoes` with his glamour girls.

"I'm bored of the hanky panky. I'm still active but it's different - I like to play dominoes with my girlfriends," The Sun quoted him, as saying.

When asked about his infamous wild nights at the Playboy mansion, the publisher who turned his men's magazines business into a worldwide entertainment and fashion empire said, "I haven't been to as many parties because I'm doing other things that are taking up my energy".

"I'm busy planning the new Playboy club at The Palms, a new Playboy club in LA," he added.

Earlier this year Hefner, who once had a harem of seven `blonde`, `busty` and `beautiful` girlfriends, told The Sun that women were the key to keeping him young.

"Having three beautiful women keeps the years off me. I would recommend it to anyone," said the tycoon, who in 1997 cut down the number to three, saying the girls got jealous.

Paris Hilton dating Andy Roddick?

LONDON, Oct 5: After dating billionaire Greek heirs, rockers and actors, hotel heiress Paris Hilton reportedly has a new man in her life - tennis champion Andy Roddick. The couple were spotted flirting at Las Vegas' trendy Tao nightclub recently, and were also seen getting hot and heavy on the VIP bed in Vegas' Pure nightclub.

A source revealed that the two were "clearly a couple" and that while the 'Star Are Blind' singer was getting "very touchy-feely", Roddick on the other hand, just "couldn't keep his eyes off her".

"They were snuggling up to each other while drinking Grey Goose vodka and shots of Patron. They were clearly a couple. She was very touchy-feely and he couldn't keep his eyes off her," The Sun quoted the source, as saying.

The couple didn't around at the nightclub for long, and after a couple of hours left the place together.

"After a couple of hours they left together," the source added. Rumours that Paris, who has enjoyed previous relationships with billionaire Greek heirs, singers and actors, was dating 24-year old Roddick started making the rounds recently when the twice Wimbledon runner-up showed up at LA's Hyde club on the same night that the 'Simple Life' star was also there.

Janet Jackson hasn't yet forgiven Timberlake for Nipplegate fiasco

WASHINGTON, Sept 29: More than two and a half years after her breast was exposed to nearly 100 million viewers during the Super Bowl, Janet Jackson has refused to speak to former pal Justin Timberlake for distancing himself from the debacle immediately.

The 'All For You' singer still feels sore that she was left to bear the brunt of the backlash following the infamous televised wardrobe malfunction, after her dance partner Timberlake refused to support her in the aftermath.

Though the former `N Sync singer has since publicly apologised to Jackson for his actions, and has made every effort to get in touch with her personally, she feels that it is not yet time for her to get back on friendly terms with him.

"We haven`t spoken but he has reached out to speak with me. Friendship is very important to me and (there are) certain things you just don`t do to friends and in my own time I`ll give him a call. "Certain things were said, supposedly... during that whole fiasco, I had heard, and (he was) kinda leaving you out there hanging (sic)," Contactmusic quoted her as saying at the Oprah Winfrey show.

The 'Sexyback' singer had recently blasted the US media for being unfair after it singled out Janet Jackson to blame for the incident, claiming they did it because she is a black woman and he is a white man.

"I probably got 10 per cent of the blame and that says something about society. I think that America's harsher on women and I think that America's unfairly harsh on ethnic people," he said.

However he also admitted that he did the wrong thing by taking the opportunity to distance himself from the scandal and Janet herself. "I didn't handle it the best way I could have but you get your bumps and bruises from it and you learn".

Beckinsale does a Monroe skirt-swirl in Germany

LONDON, Sept 29: British beauty Kate Beckinsale showed off more than she intended when she inadvertently did a Marilyn Monroe at the Berlin premiere of her latest flick.

A gust of wind apparently caught the 'Underworld' actress' satin dress - mimicking a famous scene from Monroe's flick 'The Seven Year Itch', in which the blonde bombshell's character has her skirt blown upwards revealing her underwear, reports the Daily Mail.

Beckinsale was in Germany to attend the premiere of 'Click', in which she stars opposite Hollywood funnyman Adam Sandler.

The flick tells the story of a man who discovers a remote control which lets him time travel.

The big-screen is not the only place fans will get to see the actress in the coming months, for rumours have been circulating that she is planning a return to the London stage.

The actress is also planning to a more permanent return to her home country with her director hubby Len Wiseman, and daughter Lily.

Shocking sex secrets!

NEW YORK, Sept 15: Tom Cruise's powerful legal team might try to stop porn producer Paul Barresi's book which is expected to make shocking revelations about the actor's sex life. According to newsweek.com, Barresi is writing a book called Pellicano's Enforcer about how he helped former private eye Anthony Pellicano protect celebrities from negative stories.

In one chapter, which is posted on the net, he tells how someone came to him trying to sell him a story about Cruise and how Cruise's team got that story killed.

Barresi does not prove or disprove the claim and a source said: "Cruise cannot be happy with the story. It's been a tough time for Cruise and my bet is that his lawyers are going to come out with both guns blazing - legally speaking of course."

Cruise's lawyer said that the claims made by Barresi are false and "we can prove it". He added: "If Mr. Barresi were to publish what we have seen on that website, I absolutely would recommend appropriate legal action against both Mr. Barresi and the publisher."
