So I came across an article about some guy who got penile cancer, so I looked up things like symptoms, risk factors and one of them is poor hygeine. Apparantly you're supposed to roll back the foreskin and clean it each time you wash. I'm 17 and I have never pulled mine back at all let alone wash it properly. This is because the thought of doing it and exposing or accidently touching "it" naked makes me want to heave. I couldn't think of many things more disgusting.
Now I fear for I'll get penile cancer at some point in the future. It happens to 1 in 493 men according to cancer research, but it has to happen to someone.
