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.'

Impregnation (孕ませ) is a fetish tag focused on the act of getting a character pregnant. This often involves detailed internal views (x-ray) showing ejaculation and fertilization. The tag is closely related to 'nakadashi' and 'pregnancy' but specifically focuses on the conception moment rather than the resulting pregnancy. It's a significant fetish category with its own dedicated audience.

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.'
