Men take longer steps than women, and their hips don't really swing when they walk. But women's hips swing when they walk. If you walk with your legs kind of far apart, it works pretty well to stop your hips from swinging, I think. I'm not completely sure. I walk like a guy, and that's how I do it. But I'm double jointed in my legs, so I think that may have something to do with the way I walk. Sorry that I'm not much help lol Also, when guys walk they swing their arms differently or not at all, and they keep their head up so that they're looking straight ahead. Another thing I've heard is that girls move out of the way for other people when they're walking on a crowded sidewalk, but guys don't usually.
