Yea it's normal too hurt. They should have gave you some numbing spray and a water bottle. The blood drying on it makes it hurt more so wash with warm water (you spray yourself with the water bottle) and I emphasized warm water cold water is a terrible mistake. I'd do it every time you pee to keep blood from drying on it then spray with the numbing spray. If they didn't give it to you they sell it at Wal-Mart with the antiseptic creams and such.
But is it normal that It hurt?
Normal. It takes 3 years to fully recover from childbirth
