Pornographic magazines, sometimes known as ault magazines, sex magazines, top-shelf magazines, blue books, or stick mags are magazines that contain content of a sexual nature, typically regarded as pornography. Such publications provide photographs or other illustrations of nudity and sexual activities, including oral sex, sexual intercourse, anal sex, and other various forms of such activities. Most often, these magazines contain photographs of attractive women and/or men. These magazines primarily serve to stimulate sexual thoughts and emotions. Some magazines are very general in their variety of illustrations, while others may be more specific and focus on particular activities, fetishes, or parts of the anatomy. Adult magazines are mainly aimed towards men, as males populate the vast majority of the market.
