These anime are categorized as Shounen-ai. Boys' Love or BL in Japan, is a genre that depicts homosexual relationships between men. Japan typically uses this single category for all forms of these relationships, sexual or not. In the West, the term Shounen-ai categorizes stories that focus on the emotional aspects of the relationships, while Yaoi categorizes more of the sexual aspects, such as Smut or explicit content. As Anime-Planet's audience is mostly based in the West, we use the Western definition for both Yaoi and Shounen-ai. See BL for a list of both titles.
