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.'

Rape (レイプ) is a content tag indicating non-consensual sexual activity. In doujinshi, this ranges from forceful scenes to fantasy scenarios. The tag is used for content where sexual acts occur without consent from one or more participants. It's important to distinguish this as a fictional content tag — all characters are depicted as adults in the artistic context. The tag frequently appears in darker genres and is often paired with tags like 'bondage,' 'mind break,' and 'dark skin.'
