M/M

Stories in which the erotic encounters and/or focus involves two men together (or wanting to be together).

Note on stories involving multiple sets of characters: Categories apply to the narrative at any given point. If a story involves Andy wanting to be with Bob, and Charlie wanting to be with Dave, it’s M/M, not M/M/M. If Andy and Bob hook up with Evan, then at that point it becomes M/M/M.
