But men will often send such photos unsolicited to women they're either not in a relationship with or they don't even know. Kort said men just don't send these types of pictures to women either. "Many straight men will send pictures of the genitals to gay men for validation as well and enjoy knowing that it has aroused somebody else and makes them feel sexy and wanted. "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. "Because it is often unsolicited dominance seeking, guys genital pics are far more often regarded as aggressive."
