Now that we carry mobile phones with us at all times, sexy messages and photographs can be exchanged in a way that they never could before. Sexting is so common that apps have been developed to allow people to ‘sext’ strangers based on locality, shared interests and other filters. It has become a new dating tool, embracing men and women in all kinds of relationships. This programme meets couples who use sexting to spice up their marriages, singles looking for love by sexting random strangers and sexting virgins who give it a go for the first time.
