If you have spent much time at all reading and studying the issue of sex addiction and pornography you most likely have come across the linked interview with Ted Bundy conducted by Dr. James Dobson.  If you have not seen or read the interview it is eye opening information on the topic of pornography and sexual acting out.

I am not naive enough to claim this is the fate of everyone involved in sexual addiction (fill in your own terminology), but it is a vivid example of how behavior can escalate to unanticipated proportions within ones life.
