Put this one on the list of "books I wouldn't have thought to pick up if not for work." Dick Fight Island is basically what it sounds like - a battle manga about guys waging war with their wangs, albeit perhaps not in the way you're thinking. Then again, it's published by SuBLime, so maybe it's exactly the way you're thinking - because if you've ever read a shounen battle manga and thought, "Gee, I love all of this homoerotic subtext," then you are about to become one very, very happy reader.
And you know what? It's actually kind of fun. It's not my usual thing, but it has a good sense of humor about its ludicrous factor (in fact, I'd argue that it's deliberately silly), and there are a couple of genuinely sweet romance subplots. (Plus it's largely uncensored, which will make a difference to some readers.) I wouldn't suggest it for everyone, but if you're into goofy BL, this is a surprising amount of insane fun.
