Warning: Graphic/offensive content
A woman shares two different pictures of her boyfriend's penis, both showing glow sticks inserted through holes left from piercings.
She is curious to see if anyone else has partners with "random holes in their appendages" and explains the glow sticks were inserted as a party trick recently.
An apology is also issued to readers, because they might not be aware of her boyfriend's hidden talents.
It is unclear if the man has given his consent for the picture to be shared online, which may be a cause for concern given you can easily find his identity by clicking on her profile.
While a man making his genitalia glow at a party may be less likely to care about his old fella making the rounds online, there are countless other pictures of penises being shared in this secret, female-only facebook group.
In an age where men are rightly condemned for sending unsolicited pictures of their genitalia to women, it seems women sharing pictures of men's penises with each other is fair game, even if the men have not consented.
The hidden group, known as Bad Girls Advice, has more than 200,000 members and is governed by a long list of rules.
Content shared on the group includes graphic sexual discussions and images of men's bodies, detailed accounts of intimate relationships, and discussion about violence against men. In one post a member discusses stabbing her partner with a fork and driving into him with her car.
The posts include countless naked images of men that appear to be shared without consent, many of them the subject of ridicule from the female members.
In cases where men do know their pictures have been published, they are powerless to have them removed or have right of reply because the group is limited exclusively to females who must be invited.
The overarching rule for the group is one of secrecy, with threats of punishment for those who do not abide.
"BGA is a group designed for a specific audience. We want bga filled with truly entertaining, shocking, R-rated pics/stories, hilarious dark humour and offensive content," the rules read.
"If you see something you do not agree with or something that offends you, you have two choices: ignore it and scroll by or get blocked from BGA permanently."
Of all of the rules, one was broken by my anonymous insider, so this group could become public knowledge.
"Do not f***** screen or share BGA without anyone outside of BGA," rule number six reads.
"What happens in group, stays in group. If you want your friends to see, please add them in! Sharing any BGA content outside the group will get you blocked immediately. Don't show you man/mates or f**kbois. It's called Bad Girls Advice for a reason."
With my anonymous insider willing to spill the beans on the inner-workings of this large online community, I set about finding what was being posted in this hidden group.
"There's a lot of memes, girls talking about f**king, a couple of articles about sexual experiences and sex toy advice," she told news.com.au.
"There's a 'date a mate' thread where people post a friend who they think is fair game for the girls there to message. This is both horrifying and interesting to go through.
"There is also a lot of stories about failed sexploits or guys asking for weird shit, too."
Interested to find out more, I asked her to break the rules and send me some screenshots showing the type of content she had referred too and the results were varied.
One of the most common things shared in group is pictures of male genitalia, which have been sent to or taken by the person posting.
While most don't identify the owner of the genitals, the pictures are grilled by members who poke fun at everything from the shape, size and grooming of the penis.
But the threads are not just about "dick pics". Other posts purport to help set friends up with eligible men including the "official date a mate and sex a friend thread".
As the name suggests, the thread is about helping getting their friends laid.
Users are asked to post a photo of their friend, along with name, age, location and ways to contact them.
In addition to women helping to hook up friends, there are multiple posts sharing sexploits.
An example of this is the woman who said she had a man years ago who "sounded like a koala's mating call" when he ejaculated. She goes on to say the experience made her "die of laughter".
In one nsfw post, a member tells how she tried to set up a steamy threesome with her boyfriend and another female from Tinder.
She tells how she booked a hotel, only to have the female ghost the couple the day of the event.
Upset, she asks if there are any girls in the group from Brisbane that want to get "freaky on the weekend".
While many posts appear to be a harmless exchange of anecdotes, some more troubling and appear to condone domestic violence against men.
In one thread, a woman explains she is in a fit of rage with her partner and wants to "punch him in the c**k and stab him in the leg with a fork", before asking what the craziest thing members have done to a male in a fit of rage.
The post was met with numerous responses, some troubling.
"Threw a potato at his head, threw a mug at his head, threw a stubby at his head, threw a rock at his very expensive v8 (sensing a pattern)," responded one user.
"Stabbed with a fork, reversed over him in a car, threw him out of the car, punched him in the nose, threw bowls, remotes or wateva [sic] at his head," wrote another.
"I'm legit laughing u [sic] bitches r [sic] off tap. I love this page," replied one user.
Bad Girls Advice has some disturbing parallels to Blokes Advice, a secret Australian Facebook group where men entertain each other with descriptions of rape, revenge porn and violence against women.
The group was eventually shut down, but another secret page was formed within days of dismantling its predecessor.
