I have a small new insight into shaving that I am going to test out over the next few weeks. I have noticed pubic hair dulls razors really quickly, so I am going to get some of the really cheap disposable razors and try changing them out every 2-3 shaves and see if it help cut down on irritation. I love my vibrating razor, but the heads for it are just to expensive to change as often as needed when shaving down there.
