I shave my shaft and balls at least once a week......used to use a triple edge blade, but then my wife started using the "Intuition" razor for her legs.....So I got one and it works perfect! The razor is encircled with soap, so it provides lubricant while shaving, and is especially good around the curves of the balls......It's perfect for shaving in the shower, just make sure to get semi-erect and take it slow and easy until you get used to it...
