One woman who has recieved unsolicted images of men's genitals says she believes it is a control issue.
The practice, known as cyber-flashing or 'dick pics' has become more common with the growing use of dating apps.
Usually a woman will match with a man on one these apps and then they'll swap numbers. But on ocassion the man will send an unsolicted nude picture.
Sending such images is illegal under Irish law.
