I firmly believe that sex when you are a child does not make you a pedophile. I think some pedophiles have sex when they are young and some do not. Some people who had sex when they were children end up becoming pedophiles and some do not. Correlation does not equal causation. In other words, just because someone had sex when they were a child and are a pedophile it does not mean that one caused the other.

On another note: why do you keep calling sex abuse? Some sex is abuse and some abuse is sexual in nature but not all sex is abusive no matter the age of the person.
