Bondage (緊縛, kinbaku) is a fetish tag covering restraint and bondage scenarios in doujinshi. This ranges from simple rope bondage to elaborate suspension scenes. The artistic treatment varies from realistic kinbaku (Japanese rope bondage) to stylized fantasy restraints. The tag covers consensual BDSM scenarios as well as non-consensual restraint (when paired with 'rape'). Related tags include 'collar,' 'handcuffs,' and 'femdom.'

Futanari (ふたなり) refers to characters with both male and female sexual characteristics — typically female-presenting characters with a penis. This is a significant genre in hentai with its own dedicated audience. The tag covers a wide range from characters with both sets of genitalia to characters who are essentially female with male genitalia. Artistic treatment varies from realistic to highly stylized. Related tags include 'males only' (for futanari-only content) and 'yuri.'

Yuri (百合) refers to female-female romantic or sexual content. Unlike 'lesbian' which implies real-world orientation, yuri is a genre term specific to Japanese media. The content ranges from soft romantic tension to explicit sexual scenes. Yuri has its own rich ecosystem of tropes and character dynamics. Related tags include 'futanari,' ' ffm threesome,' and 'sole female.'
