Преимущественно для парней, как и яой для девушек

yaoi (an acronym that stands for yama nashi, ochi nashi, imi nashi, or "no climax, no resolution, no meaning," although it is joked that it stands for YAmete, Oshiri Itai, or "stop, my butt hurts") began as self-published doujinshi, written by women for women, about men in a sexual relationship, usually configured with one character being dominant, who is called the top, and one character being submissive, called the bottom. Like slash fiction, it was a genre about two popular male characters getting it on, although later, the main characters concerned became bishounen, beautiful and often feminized boys. (There is much debate among fans of this genre as to which popular male character is the top and which is the bottom; to put it in a superhero perspective, Wolverine would be the top and Spider-Man would be the bottom in these comics.) Currently in Japan, the term yaoi has negative connotations and now specifically refers to doujinshi and the most sexually explicit M/M material for women.
