Nudity

Whips and chains are all the rage in San Francisco today (most days, really) -- but Instagram ain't down with the BDSM celebration.

The Folsom Street Fair -- San Fran's annual BDSM and leather subculture festival -- is being heavily policed by the social app. The reason is pretty obvious ... there's a ton of nudity at the event, and apparently several inappropriate photos got posted, at least temporarily.

Instagram put up a disclaimer saying certain pics had been removed.

Here's the thing ... the ones that were deemed kosher are still pretty over the top -- unless you're used to seeing dudes wrapped head-to-toe in chains and leather thongs.

If you're not used to it ... here's your chance. Enjoy!.

A third year law student is taking on Facebook in court, claiming the social network made him look like a sex-crazed maniac.

Franco Caraccioli claims someone created a fake profile under the name Franco Caracciolijerkingman and packed it with pornographic images.

Franco says he caught wind when the fake account blasted him and all his buddies with friend requests.

He says he was super embarrassed and contacted Facebook, demanding they 86 it. Facebook sent him an email saying they found nothing wrong with the profile because it's in-line with Facebook community standards.

According to Franco, it was belatedly taken down, but only after he threatened legal action.

But that's not enough for Franco. He's suing Facebook for more than $1 million, and he's repping himself.

Two topless women from the feminist group, FEMEN, stormed the stage of a Muslim conference during a "wife beating" discussion in France Sunday.

The conference about Islam’s teachings took place in Pontoise, France ... with one topic discussing whether men are allowed to beat their wives.

During the discussion, two FEMEN activists jumped on stage and pulled the microphone away from the shocked speakers. Security guards quickly pulled the 2 women off stage ... appearing to kick one of them as she was dragged away.

FEMEN naked protests, which was originally founded in 2008 in Ukraine, have popped up in many different countries ... normally with messages painted across their bodies.

During this protest one message painted across one of the activist's chest is reported to have read “nobody makes me submit.”

The womens identities are not yet known.

Lenny Kravitz wasn't taking any chances Friday night at the Greek Theatre in L.A. ...he was covered from head to toe.

No chance of another special guest star ... like the one that popped out of his leather pants which split last month during a concert in Stockholm.

Roberto Esquivel Cabrera claims he was tormented by U.S. prison guards because of his enormous penis.

Turns out Cabrera is a felon who served time in a Mississippi pen for entering the U.S. illegally. The penalty was especially harsh because he had been convicted of felony forgery years before in the U.S.

During his prison stay between 2003 and 2011, Cabrera filed a lawsuit claiming mistreatment. He says in handwritten documents guards treated him like a freak, demanding to take pics of his 19-inch penis, which they cruelly nicknamed "Anaconda."

Cabrera says a female guard became a Peeping Tom as he changed his clothes. He says gay prison guards would grab his penis while searching him ... he did not explain why he says they're gay.

Cabrera goes on to say he was disciplined once when his penis was hanging out of his shorts ... something he says was beyond his control.

He says in the docs he was denied special underwear which he says he needed because of his condition.

The prison guards tell a different story, claiming he would masturbate in his cell and would often expose himself for shock value.

The lawsuit was dismissed.

Roberto was released in 2011 and sent back to Mexico.

Karlie Redd is taking the high road when it comes to stripping for cameras, opting for Playboy instead of porn.

The ‘Love & Hip Hop: ATL’ star will be getting fully naked for Playboy Plus, the magazine’s NSFW sister site (act like you don’t know).

Karlie thinks the Playboy route is classier than the Vivid route ... the company offered her $25k for a sex tape, which she seriously considered but ultimately rejected.

Playboy Plus says they'll shoot Karlie next month and the pics will go public this fall. They plan on putting Karlie in the celebrity section where she'll be right at home with Kim Kardashian and Madonna.

Lenny Kravitz will NOT 86 leather pants from his tour, despite the biggest wardrobe malfunction in history.

Our sources say, Lenny was privately horrified his penis made a grand entrance during a concert after his tight leather pants exploded.

A lesser man might hang up the leather for a safer pair of trousers, but the 51-year-old is not deterred. We're told he will continue to wear leather.

Some thought he'd hold a grudge against Saint Laurent, the manufacturer. But Lenny is chalking it up to a bad pair, and will continue to wear the duds during his show.

Lenny continued his European tour Thursday in Denmark. Come to think of it, if it happens in Denmark it's probably no big deal.

Lenny Kravitz had the worst wardrobe malfunction of all-time -- or maybe the best -- when his leather pants ripped completely open onstage ... and his junk fell out.

Luckily, Lenny had a back-up pair of pants during his Monday show in Stockholm -- so he was able to do a quick wardrobe change and finish the concert. Even luckier ... he's got no reason to be shy.

Encore!

Remember when LeBron James accidentally flashed his dong on live TV during the NBA Finals? Well, it ruined one viewer's Laser Tag date ... this according to the FCC.

John Cena naked might be a glorious thing to behold, but his fellow WWE star Big Show draws the line at seeing the man's semi-erect penis on a massive movie screen.

We got Big Show at LAX, and filled him on (spoiler alert) Cena's scene in "Trainwreck" where he shows off a good bit of his championship goods. The big man's reaction is priceless -- at first, he's totally comfortable, but the details of the scene push him over the edge ... in a funny way.

Also comical -- our photog suggested Big Show, who played college hoops at Wichita State, could have taken Shaquille O'Neal back in the day.

Rihanna does her best work unrestrained, which may be why her nipples are about to bust free at a NYC recording studio.

The singer was wearing pink satin nightwear and a white lace bra as she sauntered inside the studio.

Hope he enjoyed banging on the beach -- 'cause a Florida man's gonna be locked up in prison for the next 2 and a half years for doing the deed.

Jose Caballero was nabbed for having sex last summer with his girlfriend, Elissa Alvarez outside Tampa. Problem is these rocket scientists were banging in front of a woman with a camera -- and more importantly -- in front of little kids.

Witnesses say they weren't exactly quiet or discreet during the 25 minute encounter.

Both were found guilty of lewd or lascivious exhibition in front of a child, a second-degree felony -- and must register as sex offenders.

Talk about an awkward conversation ... the L.A. Dodgers once "had an issue" with a pitcher who took locker room nudity WAYYYY too far -- and would hit the team snack bar with his dong out ... so says Eric Karros.

It all went down in the '90s ... and judging from the way Karros tells the story, the "issue" was more about being sanitary ... because nobody wants dirty naked parts touching the team Cracker Jacks.

NFL legend Eddie George is all about nipple equality ... telling TMZ Sports he completely supports Chrissy Teigen's war on boob censorship ... because, well, "She's on the right track."

Teigen's tatas have been all over the news ever since she posted topless pics on Instagram -- pics that Instagram took down due to its no female nipple policy.

But George says he agrees with Teigen that women aren't getting treated fairly when it comes to what they can show off in public.

"Hell, if she wants to show her nipples to the world, show the beauty behind it, I'm all for it. Save the nipple."

You can't blame LeBron James for accidentally exposing himself while adjusting his wiener on national TV ... so says The Game who says it's hard to move well when your dong's in the wrong spot.

The rapper was out in L.A. last night when we asked about King James and his royal scepter ... and that's when Game explained why the pre-game penis shirt is absolutely imperative to an NBA star.

In fact, Game says he can relate ... "You ever try to go outside and live your life but your package ain't in the right place? You gotta get that thing to the left side, jiggle it, you know what I'm sayin?"

LeBron James didn't go balls out in Game 4 of the NBA Finals ... he went dong out instead.

Moments before tip off Thursday night, LeBron went to adjust himself below the waist ... and it just so happened to be at the same time an ABC camera moved in for a close-up.

James opened his shorts a little too much ... and boom -- LeBron's penis was introduced to roughly 18.5 MILLION viewers.

If you really wanna see it ... click here -- but WARNING, it's a penis.
