Okay, I wouldn't recommend starting this manga list until you're ready for some hardcore stuff-LITERALLY, I mean HARDCORE, none of that sweet bl softness-this is pure(not really), raw, NSFW type of stuff.
You may feel your favorite manga should be gathered together into distinct categories for your own reference and, now, you can do this with a LIST. After you've created your list or lists, you can proudly recommend them to other manga fans to showcase and share your taste in manga.
