Anal intercourse is a common sexual act tag in doujinshi. It appears across nearly all genres and demographics, from vanilla romance to extreme fetish content. The artistic depiction ranges from realistic anatomy to highly stylized presentations. This tag frequently co-occurs with tags like 'nakadashi' (internal ejaculation), 'big breasts,' and various body-type tags. Some artists specialize in anal content, developing signature techniques for depicting the act. The tag covers both consensual and non-consensual scenarios depending on accompanying tags.

Lolicon (ロリコン) refers to content featuring young or young-appearing female characters. In doujinshi context, this tag indicates the presence of petite, youthful female characters. The term originates from 'Lolita complex' and is a significant demographic category in Japanese fan-made works. Content with this tag ranges from suggestive to explicit. It frequently appears alongside tags like 'small breasts,' 'defloration,' and 'schoolgirl uniform.' The tag is distinct from 'shotacon' which features young male characters.

Ahegao (アヘ顔) refers to the exaggerated facial expression of ecstasy commonly depicted in hentai. The face is typically shown with rolled-back eyes, protruding tongue, and flushed skin. This visual trope has become iconic in adult manga and is used to indicate intense pleasure or overstimulation. The tag covers both subtle and extreme versions of the expression. It frequently appears alongside tags like 'big breasts,' 'nakadashi,' and 'multiple male.'
