Sounds like too much pressure and too harsh of an angle. Most people are too used to the pressure (and angle) you have to use when using a cartridge razor. When using a DE like yours, you literally just use the weight of the razor. And the 34C is a pretty heavy razor. Make sure your angle is such that the razor isn't completely perpendicular to your face (like a cartridge razor). You have to kind of tilt DE razors when you use them. Also make sure you are stretching the skin where you shave. It really helps a ton with saftey razors.
