From experience, I've been married for fourteen years, and in those fourteen years I've had pied multiple times. We even got prescribed Viagra to help, and only one position would make me reach orgasm. My wife thought my pied was because of a brain injury I suffered from active duty. I knew it was from being involved with porn daily. I'd tried multiple times to stop viewing porn, but would fail miserably. It wasn't till I went to a married couple's rehab for sex addicts; I realized what I was doing to my family. I wasn't protecting what I loved. Today I'm over a year and a half clean from porn and masturbation and I can tell you the sex has never been so good. My erections are harder and last longer, and the O is incredibly intense. When you reach the big O, look at your woman. This burns her image into your brain as excitement, and rewires your neuro pathways.
