Blowjob (フェラチオ, fellatio) is one of the most common sexual act tags in doujinshi. It covers oral sex performed on male characters. The artistic depiction varies from realistic to stylized, with many artists developing signature techniques for depicting the act. Common visual elements include drool, tongue detail, eye contact, and depth indicators. The tag appears across virtually all genres and is frequently paired with tags like 'ahegao,' 'big breasts,' and 'sole female.'

Mosaic censorship (モザイク) refers to the pixelation or blurring applied to explicit content in Japanese published works. This is due to Japanese obscenity laws that require censorship of genitalia in published materials. The tag helps readers identify whether content is censored or uncensored. Many doujinshi are published with mosaic censorship and later 'decensored' by fans or released in uncensored versions by the artist. Related tags include 'uncensored' and 'full censorship.'

MILF (Mother I'd Like to Fuck) is a character type tag referring to mature female characters, typically mothers or maternal figures. In doujinshi, this tag indicates content featuring older women, often contrasted with younger male partners. The appeal lies in the experience and confidence of the character. The tag frequently appears alongside 'big breasts,' 'incest,' and 'sole male.'
