As many of you know, I have three cats. They are also all males. They get along very well together. Pepper tends to sleep more than Storm and Sunny so when he's sleeping the other two can play with each other. Sure they will fight like siblings occasionally but this also happens with two cats as well. Before I got my third cat Sunny, Storm was fighting with Pepper much more than he does now. He needed another cat to play with. I guess I just lucked out personality wise too. Good luck in whatever you decide to do toughCookie.
