I found a great tool that can help you stop looking at porn sites. I downloaded it, and it's been working really well for me.

Basically, ya download it, and when ya run the program, it asks for the email addresses of TWO people who will receive your history evern 2 or 4 weeks (you get to decide) and they are you're accountability partners. Then your accountability partner and you talk things over. It works really great. Check out guys!
