Yaoi (やおい) refers to male-male romantic or sexual content created primarily for a female audience. In doujinshi, yaoi works feature relationships between male characters and span a wide range from soft romance to explicit content. The genre has its own rich ecosystem of tropes, character dynamics, and artistic conventions. Yaoi is distinct from 'bara,' which is male-male content created by and for gay men. Common related tags include 'males only,' 'seme,' 'uke,' and 'anal.'

Dark skin (黒人, kokujin / 日焼け, hiyake) refers to characters with darker skin tones. This includes naturally dark-skinned characters, tanned characters (tanlines), and characters with dark skin as an artistic choice. The tag covers various ethnicities and skin tones. It's often paired with tags like 'tanlines,' 'big breasts,' and 'big ass.'

Muscle (筋肉, kinniku) refers to characters with muscular physiques. This tag covers both male and female characters with visible muscle definition. In doujinshi, this ranges from subtle athletic builds to heavily muscled bodybuilder types. The tag has grown in popularity alongside the 'gijinka' and fitness trends in fan art.
