Teens and preteens are at the heart of the social Internet interacting with others through chat, instant messaging, social networking sites, in virtual worlds and online multi-player games. It is inevitable that at an age where young people are starting to explore their sexuality offline, they will do so online in these interactive environments as well.
When most people think about sexual risk and harm on the Internet, sexual predators come to mind. Because of its sensational nature, the spectre of unscrupulous adults preying upon and sexually exploiting kids online gets a lot of media attention. Although this does happen, sensational headlines do not help us understand the nature and true extent of the problem or how to deal with it effectively.
As adults, we want to foster resilience in young people, starting when they’re young. This can be done by teaching them how to handle harassing messages or requests that make them feel uncomfortable – on the Internet or in the schoolyard – and, as they get older, by teaching them how to spot and respond to emotional manipulation. The good news is that most teens are effectively handling online requests from strangers – the bigger challenge is helping them handle sexual advances from people they know.
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.
Moral disengagement is used to describe the ways in which we convince ourselves to do something that we know is wrong, or to not do something we know is right. MediaSmarts’ research looked at the impact of four moral disengagement mechanisms:
How common young people think sexting is has been identified as one of the strongest factors influencing whether they send sexts.
