A contact magazine is a type of classified magazine that is largely or wholly dedicated to personal ads. As well as publishing the personal ads, the publishers of contact magazines often run an anonymous mail forwarding service that allows advertisers to identify themselves only with box numbers.
Many contact magazines used to be swinger or sex-contact magazines aimed at a readership of people looking for or offering casual sex. With the advent of swinger social network and other adult swinger websites, these magazines are now an anachronism. Specialized magazines also existed for those with specific sexual preferences, such as those seeking BDSM encounters, or the services of professional dominants or submissives.
