I told her a few days ago about it. Not very graphic on the details, but i confessed that i had "weird and dark fantasies" ever since i was a kid, and that it caused me to develop very poor sexual confidence. And that this, in addition with copious porn use, was the main cause of the problem.

Thankfully, she was very understanding and willing to work this though with me. I think this will help in the long run, especially if i keep away from porn indefinitely. I certainly hope so.
