To each their own, but realize that you are going against the advise of the Sex Anonymous (SA) organization, and I think they have more expertise on this subject than most everyone on this thread. SA has a plain white cover book for it's members, it's 212 pages long. On page 3 they caution the addict not to confess too early until the addict has a period of sobriety.
I honestly don’t get the logic. I’ve been in therapy for 4 years. And have had a habit of studying psychology since as long as so can remember. I can’t believe I didn’t come across the porn addiction thing sooner. But it’s clear what a huge difference accountability makes in any situation. And coming from the side of the person you are hurting trust me it’s worse the longer lies go on. Do what works for you I guess. But the science backs accountability.
