Should I tell my wife I am addicted to phone sex?

I have a problem with porn, but I have abstained and kept myself from pornographic media (got rid of my internet phone, internet at the house…). Now, I am still dealing with calling this stupid number.

I do not want to be in bondage to this behavior. I think that telling my wife would give me some accountability. What I am struggling with is not wanting to hurt her. I know she will forgive me, but I keep stalling because I think I can quit without her finding out and we can proceed with life as usual and she won’t have to get hurt.
