Shotacon (ショタコン) refers to content featuring young or young-appearing male characters. The term originates from 'Shotaro complex' (after the character Shotaro from Tetsujin 28-go). In doujinshi, this tag indicates the presence of youthful male characters in suggestive or explicit scenarios. Content ranges from innocent to explicit and is a significant demographic category. The tag is the male counterpart to 'lolicon' and often appears in yaoi (male-male) content or in heterosexual scenarios with older female partners.

Yaoi (やおい) refers to male-male romantic or sexual content created primarily for a female audience. In doujinshi, yaoi works feature relationships between male characters and span a wide range from soft romance to explicit content. The genre has its own rich ecosystem of tropes, character dynamics, and artistic conventions. Yaoi is distinct from 'bara,' which is male-male content created by and for gay men. Common related tags include 'males only,' 'seme,' 'uke,' and 'anal.'

Incest (近親相姦) refers to sexual content between family members. In doujinshi, this commonly involves siblings, parent-child relationships, or other familial pairings. The tag covers both blood-related and step-family scenarios. It's one of the most common narrative frameworks in doujinshi, often used to create dramatic tension or taboo appeal. Related tags include 'sister,' 'brother,' 'mother,' and 'father.'
