Sexual Addiction or Destructive Sexual Behaviors: What's the Difference?

Here's an article on sexual addiction.

Joe's a 45-year-old father of three, who agreed to marry after he and his wife struggled with their on-again-off-again relationship for five years prior to marrying. Like most red-blooded American males, Joe began using pornography to masturbate when he was a teenager. He started out looking at print pornography, masturbating to images of fairly wholesome young women. By the end of college he was renting videos, which became boring over time so he upped the ante by going to peep shows. Eventually, Joe crossed a personal boundary and paid for sex by getting a sexual massage.

One thing led to another and by the time he was married, he'd already been hiring escorts once a month. Joe got caught. His wife found a video of him having sex with one of the prostitutes, leaving her devastated. She now understood his ambivalence about getting married.
