Given that the sharing of genital images – colloquially known as “dick pics” – has become a widespread phenomenon, the purpose of the present study was to explore men’s motivations for sending unsolicited images of their genitalia. A secondary purpose was to investigate the personality and sexuality characteristics of men who send dick pics relative to those who do not. 1,087 men completed an online survey, which included a demographic questionnaire and measures of narcissism, exhibitionism, erotophilia-erotophobia, and sexism. Also included was a measure developed specifically for the current study exploring the motivations behind sending unsolicited genital pictures as well as reactions senders hoped to elicit from their recipients. We determined that the most frequently reported motivational category for sending genital images was a transactional mindset (i.e., motivated by hopes of receiving images in return), while the most commonly desired reaction from recipients was that of sexual excitement. Further, we determined that men who reported having sent unsolicited dick pics demonstrated higher levels of narcissism and endorsed greater ambivalent and hostile sexism than their non-sending counterparts. This study is among the first to provide empirical evidence into the motivations and personality characteristics of men who send unsolicited dick pics.
