Rebecca Mcgregor claims she receives around three unsolicited images from men every day - so has taken matters into her own hands.
A lingerie model fed up with men sending her pictures of their genitals has taken revenge by forwarding the images to their mothers.
Rebecca Mcgregor, from Aberdeen, Scotland, claims she receives around three unsolicited images from men every day.
The 21-year-old believes her job as a lingerie model and photographer could be the reason why so many are being 'disrespectful' by sending the explicit photographs.
After receiving one particularly lewd image of a naked man showing off his torso and penis - which 'was the straw that broke the camel's back' - Ms Mcgregor decided to take matters into her own hands.
She found his mother on social media and sent her a message: "Hey doll, I see you're listed as [name removed]'s mother? I think you need to have a chat with your son on how to approach women - see attached xx."
Ms Mcgregor said: "I find the men sending these images really disrespectful and it makes me uncomfortable.
"I receive them at least three times a day unsolicited and mostly, they will just send them and not even try to say hi.
"Some might try and make conversation, but generally they just send the out of the blue and they appear in my inbox.
"This is why I sent the picture to this guy's mum. It was the straw that broke the camel's back and my last option.
"I'm not really like most of the girls these days that find it amusing or laugh at it. I'm more old-fashioned. I believed that people should have to work before they get to see that kind of thing.
"Boys use the word 'grafting' nowadays to mean they are trying to win over a girl, but they're not really working because it's a case of sending images and they end up sleeping with each other straight away."
Ms Mcgregor also re-posts photos on her Facebook timeline to shame the men.
She added: "I mostly block these men right away when they send my naked images but Facebook can't really do much.
"I've thought of reporting it to the police but they've got better things to deal with.
"I suppose it's a case of if you don't want to see that sort of thing then you shouldn't go on social media, but it shouldn't be like that. These pictures just seem to be acceptable now.
"I've had very young boys sending them too - maybe 13 or 14 - and I block them straight away.
"I hope [the sender's mum] would understand why I did what I did and would explain that he shouldn't just send images like that.
"This kind of puts me off having a partner because a few of the men who have messaged me these explicit images aren't single.
