A person can determine their own sexual direction, and there are many behavioral techniques available that would allow the person to change. The theory of learned behavior permits individuals to take personal responsibility for their own behavior. We find it difficult when people try to place the responsibility for their behavior on something else. In the great American game, the blame is placed on bad parents who make bad kids. To say that my sexual responses at some level are learned is also to say that I am responsible for them.
Paedophiles can boldly and courageously affirm what they choose.
They can say that what they want is to find the best way to love. Certainly it is responsible. What I have been struck by as I have come to know more about and understand people who choose paedophilia is that they let themselves be too much defined by other people. That is usually an essentially negative definition. Paedophiles spend a lot of time and energy defending their choice.
