Pornography and Masturbation

Ben (after a pause):  Well - er - actually, I've been searching the web myself looking for help with porn addiction.

Adam: Oh. Wow! [There is an embarassed silence.] Uh - are you - er - finding anything useful?

Ben:

There's quite a lot of stuff about porn addiction. They say to treat it the same as alcoholism. "Give it all up (both porn and masturbation), take a vow of abstinence, find a self-help group, and get a sponsor."

Adam: There are self-help groups for that??

... Do you know of any?
