Typically, youth sexting occurs in three contexts: in lieu of sexual activity for younger adolescents who are not yet physically sexually active; to show interest in someone a teen would like to date; and, for sexually active youth, as proof of trust and intimacy.
Studies about the gendered aspects of sexting consistently show that while little criticism is attached to boys who send sexts, girls who do so are perceived as being sexually immoral: girls who sext are seen as using their sexuality to get public attention, while boys – even if their sexts become public – are assumed to be doing it only to get the attention of one prospective partner.
