Five stages of addiction

Early exposure.

Most guys who get addicted to porn start early. They see the stuff when they are very young, and it gets its foot in the door.
Addiction. Later comes addiction. You keep coming back to porn. It becomes a regular part of your life. You're hooked. You can't quit.

Escalation.
After a while, escalation begins. You start to look for more and more graphic porn. You start using porn that would have disgusted you when you started. Now it excites you.

Desensitization.
Eventually, you start to become numb. Even the most graphic, degrading porn doesn't excite you anymore. You become desperate to feel the same thrill again but can't find it.

Acting out sexually.
At this point, many men make a dangerous jump and start acting out sexually. They move from the paper and plastic images of porn to the real world.

When I personally got to the "acting out phase," I started fantasizing about what it would be like to actually rape a woman.

I finally tried it one night when I saw a woman who "fit" the scenario that porn had taught me to look for. I was lucky. Very lucky. I didn't go through with it. After being reported, arrested and spending some time in jail, I finally was able to begin the process of weeding out the lies in my life that porn had put there.

Other men aren't so lucky. I realize now that with just a little push, I could have gone over the edge. I could have raped that woman and then killed her to cover my tracks. That's how Ted Bundy got started. When the porn he was addicted to wasn't enough anymore, he tried the real thing — rape, and then murder. When he succeeded, he did it again. And again. Pornography addiction is very serious.
