Men who send unsolicited d*** pics may be NARCISSISTS and usually expect 'something in return'

Men who send other people unsolicited images of their genitals are likely to be more narcissistic and sexist that those who do not, psychologists have found. Researchers surveyed over a thousand men to compare the personalities and motivations of those who sent intimate images and those who did not. Rather than for personal gratification, men who share images of their genitals typically do so hoping to arouse the recipient and get images back in return. A small minority of participants reported sending the private photos in order to intentionally elicit a negative response from women. The researchers conclude that the practice can neither be construed as solely sexist or as a positive sexual outlet.
