Sole male indicates a gallery features exactly one male character. Combined with 'sole female,' this creates the classic one-on-one pairing. With multiple female characters, it creates a harem scenario. This tag is useful for filtering based on the reader's preferred dynamic — whether they want focused monogamy-style content or one male with multiple partners. The tag doesn't specify the male character's role or prominence; he could be the protagonist, a side character, or even a reluctant participant depending on the genre.

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.'

Pantyhose (パンスト, pansuto) is a more specific variant of the 'stockings' tag, specifically referring to full pantyhose rather than thigh-highs. The tag has a dedicated following who prefer the smooth, uniform look of pantyhose over separate stockings. It frequently appears alongside 'schoolgirl uniform,' 'big breasts,' and 'sole female.'
