Sex

NBA legend Michael Jordan tried to win entrance into Kennedy's vagina during a steamy dice game back in 1995 ... so says the former MTV star, who claims she was a virgin at the time.

Kennedy -- who was a huge MTV VJ back in the '90s -- details the encounter in her new book "The Kennedy Chronicles" ... explaining how she was having dinner with MJ and Russell Simmons at the Bowery Bar in NYC, when Michael broke out some dice.

Before long, Kennedy says, Jordan decided it was "time to play for something" ... and said, "If I win, you come back to my hotel room with me tonight."

Kennedy says she freaked out because she was a virgin --and imagined MJ's giant penis would "eviscerate me from the inside out" ... so she asked if they could play for Knicks tickets instead.

And that's when Jordan allegedly reminded Kennedy he had a wife -- and offered her Nets tickets as a consolation.

"Sure, he'll filet my vag like a sea bass if he won at dice on a men's room floor," Kennedy writes ... "but as soon as I want basketball tickets he's a Promise Keeper? Whatevs."

Kennedy says she won the dice game anyway -- so her vag was never in any real danger.

We reached out to MJ for comment -- so far, no word back.

Marvin Gaye's son loves his father's music so much, he and his wife get busy to it -- and just to drive the point home, MG3 presented our camera guy with exhibit A ... his son!

Umm ... gross, Dad.

The HIV-positive former male porn star known as "Buttman" couldn't possibly have put a female XXX actress at risk -- because he never had sex with her ... so claims his porn company.

TMZ broke the story ... porn star Katie Summers has filed a lawsuit against Buttman (real name John Stagliano) as well as his company, Evil Angel Productions, claiming Stagliano never disclosed he was HIV-positive before co-starring with her in sexual scenes.

Summers says she performed alongside Stagliano in "Buttman's Stretch Class #4" back in 2007, and the role involved sexual interaction.

But a rep for Evil Angel Productions has posted Katie's scene from the movie online ... and it doesn't show ANY penetration.

The scene features touching for sure ... but no genital-to-genital contact. As far as we know, you can't get HIV from what's depicted in the flick. The rep says, "It's the equivalent of shaking hands."

In the interest of full disclosure ... Evil Angel posted the entire scene on their website.

A popular porn star who appeared in the movie "Buttman's Stretch Class #4" is suing the male lead (Buttman) ... claiming he failed to disclose that he was HIV positive before they shot sex scenes.

The woman behind the lawsuit is Katie Summers -- real name Katherine Howard -- who claims she was paid to appear in the film back in 2009 ... and the role involved sexual interaction with John Stagliano (aka Buttman).

In Katie's lawsuit, filed in L.A. County Superior Court and obtained by TMZ, the porn star claims Stagliano had known he was HIV positive since 1997 ... but failed to disclose that information before they shot their sex scenes for the movie.

FYI -- Stagliano has been open about his condition for years.

Still, Katie claims she didn't find out about Stagliano's condition until 2012 ... 3 years after they shot the movie.

In her suit, Summers does not say if she is HIV positive.

Summers is suing for negligence, intentional infliction of emotional distress and sexual battery. She's also suing John's production company -- Evil Angel Productions -- which produced the flick.

Joe Francis and his hot blonde GF can't thank Steve Hirsch enough for snatching their sex tape off the market -- in fact, Joe's GF has even sent the Vivid honcho a thank-you letter, gushing about how Steve kept her private parts ... private.

TMZ has obtained a copy of the letter Abbey Wilson sent to Hirsch. Here's the transcript:

As we reported, a sex tape featuring Wilson and the "Girls Gone Wild" honcho was being shopped to various media outlets. Francis had threatened to sue everyone and their mother over the tape, claiming it was stolen from Wilson's iPad.

When the person selling the tape went to Vivid, Hirsch did Francis a solid and purchased it (for an unknown sum). He then returned the footage to Francis and promised never to release it.

It was an especially big deal for Abbey and Francis ... because neither has ever appeared naked on the Internet (shocking, we know).

Justin Bieber might be getting handfuls of Miley Cyrus' Montantas -- which would totally ruin the sex appeal points she just earned with that insane twerking video ... almost.

Yep ... it's that good.

Kanye West insists he did NOT cheat on Kim Kardashian with a Canadian model/bartender -- telling TMZ, the woman accusing him of being unfaithful is just out for some easy publicity.

24-year-old Leyla Ghobadi recently did an interview claiming she met Kanye at one of his concerts in July 2012 -- three months after Kim and Kanye began dating. She says Kanye had his security pick her out of the crowd and they went for drinks after.

She claims they later engaged in two sexual encounters -- one while Kim was pregnant -- and that Kanye confessed his relationship to Kim was a sham in order to increase his fan base.

But a rep for Kanye says it's all BS -- telling us, "This most recent attack on Kanye West and his family is totally without merit. It's a blatant attempt by a misguided individual who is clearly seeking publicity, and another in a series of malicious stories drummed up by non-credible 'news' sources."

The rep adds, "This is a sad attempt to hurt two people trying to live their lives."

Matt Damon's gay sex skills are OFF THE CHARTS ... at least in his new Liberace movie "Behind the Candelabra" ... so says Liberace's real ex-lover Scott Thorson.

Thorson was out in NYC yesterday when we asked about the famous sex scene in the movie -- when Matt unleashes the fury on a buck-naked Michael Douglas -- and Thorson replied, "Matt sure can pound!!!"

Thorson says he was pleased as punch at the way Matt portrayed him in the movie -- but there was some collateral damage ... Thorson says, "I bet you Catherine [Zeta-Jones] is a little jealous."

It's your typical love story ...

Man walks into a bar ...

Man orders a beer ...

Man has simulated sex with a big, black inflatable woman ...

And it all happened to "Deadliest Catch" star Scott Campbell, Jr. -- who hit up a bowling alley in Kodiak, Alaska a few weeks ago when a bachelor party rolled in ... sex doll in tow.

So ... naturally ... Scott pretended to have sex with it.

We're told everyone had a blast -- including the doll.

Michael Douglas' hypothesis that oral sex caused his throat cancer has sent Americans reeling. So we gotta ask ...

"Girls Gone Wild" founder Joe Francis is the star of a brand new hardcore sex tape ... problem is, he claims it was STOLEN from his longtime GF ... and now he's threatening legal action, TMZ has learned.

The footage -- shot several weeks ago -- features Francis getting down and dirty with his girlfriend Abbey Wilson -- who (deservedly) won the GGW "Search for the Hottest Girl in America" contest back in 2012.

We know ... the footage contains material from several sexual liaisons ... and it's currently being shopped to various media outlets.

Francis tells TMZ ... he has NOTHING to do with the tape's release -- and, ironically, he's trying desperately to stop it from going public by THREATENING the person who has it.

Joe claims the footage was ripped off of Abbey's iPad -- which was recently stolen from her bag at LAX.

Francis' lawyer, David Houston, tells TMZ, "It is not only unfortunate, but it is a crime. As such, this office will take all necessary steps to determine who in fact has done this and who is attempting to distribute the video."

Joe's attorney says they have already contacted the authorities -- and want to deliver a strong warning to whoever has the footage:

"When we catch you, we will see that you are prosecuted to the fullest extent of both the criminal and civil laws."

If Miranda Kerr could ditch that lucky bastard Orlando Bloom for some sweet lady love ... the super hot supermodel tells TMZ ... there's only ONE WOMAN that could satisfy her craving.

Kerr hit NYC Tuesday -- in a skin tight dress -- when we asked the most important question of her career: DOES SHE HAVE A GIRL CRUSH?

Turns out ... yes, yes she does.

BONUS -- Kerr's fantasy chick HAS been in a girl-girl relationship in the past.

Snooki says she lost her virginity at age 14 ... because she was bored ... and says the guy who took her V-card was a total jerk.

The "Jersey Shore" star spilled her guts during an interview with YourTango.com ... explaining, "I was 14. I mean, in upstate New York there's really nothing to do up there but experiment."

She continued, "He was a senior, and I thought he liked me but turned out he was just a jerk. So, it was terrible."

Snooki never names the guy ... but in previous interviews she's torn him apart -- saying, "I definitely regret my first time. It sucked."

Fish and chips ... Crumpets ... Russell Brand ... hating the Irish -- these are things British people LOVE. Oral sex, however, does not belong on that list ... so says authentic British person Lisa Vanderpump.

In related news ... Lisa shot back at a report someone ate box at her restaurant -- cardboard box that is.

LV says the allegation that a patron found cardboard in a Villa Blanca salad is ridiculous ... but says even if it were true, the patron should be GRATEFUL ... 'cause cardboard is high in fiber.

Michael Douglas' ex-wife wants to make something perfectly clear -- eating out was safe when he was married to her.

Douglas told a British paper over the weekend ... his 2010 throat cancer was "caused by HPV [human papillomavirus], which actually comes about from cunnilingus."

Diandra Douglas -- whose epic divorce from Michael in 2000 was one of the richest marital settlements in history -- tells TMZ she does NOT have HPV ... period.

Nathaniel Marshall -- who made the top 36 on season 8 of "American Idol" in 2009 -- is now trying his hand (and a few other appendages) at a new career ... gay porn.

Marshall, now using the porn name Jadyn Daniels, is appearing in a film called "Men Caught on Video 2" which became available just yesterday. The movie does not appear to have much of a plot, so if you like your porn with a gripping story ... this is not the one for you.

Marshall/Daniels isn't the first reality star to transition into gay porn -- Steven Daigle, who appeared in "Big Brother 10," moved into the gay XXX biz 18 months after he left the show.
