New York psychotherapist Jeannette Stern said this misperception is also fueled by men’s attachment to their private parts.

“I think men, generally more than women, feel a connection to their genitalia and want the person they are interested in sexually to share that interest,” said Stern. “I do think that men perceive this as being more pleasurable to the recipient than it often is.”

Some men get a rush from sharing photos of their private parts with complete strangers, Katehakis, the clinical director says. They often do it through what’s known as cyberflashing.

Some men will use the iPhone’s AirDrop feature to do this. AirDrop lets iPhone users receive photos from nearby people if the feature is turned on and set to receive pictures from everyone.
