The yaoi hole (Japanese: やおい穴, romanized: yaoi-ana) is a concept in yaoi, a genre of fictional media depicting homoerotic relations between men aimed at a female audience, that supposes the existence of a male sexual organ that is neither a penis nor an anus. The concept arose from depictions of anal sex in some yaoi works that appeared to defy typical anatomy and physiology, such as representations of penetrative sex in positions that do not correspond to the location of the receiving partner's anus. The yaoi hole as a phenomenon has been alternately considered as reflecting a lack of understanding about male anatomy and anal sex possessed by the (mostly female and heterosexual) writers of early yaoi, and as an intentional exaggeration reflecting a desire for fantasy over realism in pornographic fiction narratives.
