A number have suffered the consequences of sending nudes to the wrong person.
One woman wrote: "I posted one to my now ex and didn't realise it was posted on "my story" messenger until my friend text me telling me. He showed all our mates...so embarrassing!!!!!!"
Others revealed that some recipients of their nudes have held the images to use as blackmail, with men asking for sex or face the consequences of having their image spread on social media.
"One guy I sent my nude to turned nasty. Threatened to send my nudes to all my mates and his boys if I didn't fool around with him. Sucks when you're put in that position. I've never sent nudes since," one woman wrote.
Another horrifying confession was the man who revealed he accidentally sent a nude picture of himself to his own mother.
The man explained he was on Facebook messenger and had two chats up at the same time, one with his girlfriend and one with his mother.
"So... I did the unthinkable... I was sexting my girlfriend and thought I'd be a cheeky fella and send her a nude. But while I was busy taking photos my mum messaged me, and instead of sending the dick pic to my girlfriend I accidentally sent it to my mum!!!
"Omg, seriously, there is no coming back from that. I tried to say my mates had played a disgusting prank on me but we both know I just f**ked up big time. I couldn't look my mum in the eye for months. Even my girlfriend is embarrassed."
