We know that young people are accessing explicit content online. We know less about how this exposure is impacting their attitudes and behaviours. If kids are finding good and accurate information about sexual health or healthy relationships that’s a positive thing, but if the bulk of their exposure is to pornography, then they may be receiving distorted – or even violent and deviant – messages about relationships and sexual behaviour.
The last few weeks have shed an unprecedented light on the use of digital media to spread and inspire hatred. Michael Zehaf-Bibeau, the perpetrator in the attacks on Canada’s National War Memorial and Parliament buildings, appears to have been motivated in part by exposure to online postings by a self-described member of the Islamic state, and the Federal government has already stated that it intends to create tools to remove online content that promotes the “proliferation of terrorism.”
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.
There is little evidence that sending sexts is by itself a risky act: for example, one study done with American university students found that many reported positive experiences. 
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. 
Parents, schools and law enforcement agencies are grappling with how best to respond to this issue. In the United States, sexting amongst youth has resulted in teens facing child pornography charges.
Sexting is defined as sending and receiving sexual, nude and semi-nude images electronically. While there is evidence that sending sexts is not by itself a harmful activity, significant harm can be done when these sexts are shared without the original sender’s consent.
