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.

Nakadashi (中出し) literally means 'internal ejaculation' and refers to creampie scenes in doujinshi. It's one of the most common sexual act tags, appearing in over 120k galleries. The tag covers vaginal internal ejaculation specifically. In narrative terms, nakadashi often serves as a climactic moment and may be tied to plot elements like pregnancy, impregnation, or relationship escalation. Artists frequently emphasize the visual aspect with detailed internal views (often using x-ray techniques). Related tags include 'impregnation,' 'creampie,' and 'internal cum shot.'

Stockings (ストッキング) is a highly popular fetish tag focusing on thigh-high stockings, pantyhose, and similar legwear. This tag has a dedicated following due to the aesthetic appeal of stockings in illustration — artists often use them to accentuate leg lines, create contrast with skin, and add visual texture. The tag covers various styles including thigh-highs, garter stockings, pantyhose, and knee-highs. It appears across all genres and is often paired with 'sole female,' 'big breasts,' and 'schoolgirl uniform.' Some artists are known specifically for their detailed stocking artwork.
