I then tried to quit again. I went 5 days, and then 4 days, and then gave up on the idea, resigning myself to immense sexual activity. Every month or so, I'll go on a complete rampage with as many as 10 orgasms a day for 2-3 days, rarely coming out of my room. Sometimes it even interferes with food.
My sexual tastes have grown increasingly complex, sometimes illegal, sometimes not outwardly sexual at all (example, the thought of loneliness in a girl). It has changed how I look at nearly everything, but I'm not ready to conclude that it has been for the worse.
I had sex for the first time this week. I didn't climax. My parter had no issues but I was completely uninterested, which is interesting because I had been looking forward (greatly) to the encounter for more than a week. But when it finally happened... complete disinterest. I did my best to think of porn and at least play along, but part of me felt that was more rude than just failing to climax so I sat back and let my partner enjoy her share. ED was no issue.
It's worth adding that I had never met the girl before, seen pics and talked via phone but never met in person. I had little (if any) emotional attraction to the girl, and for this reason specifically I'm not very worried. It just caught my attention because I would never have guessed that a 19yo boy would go through 40 minutes of sex with an attractive girl and not climax.
Since then I've been more motivated to quit, but I'm still not ready to conclude that porn has been a negative or bad experience. It has consistently given me a lot to think about, especially watching my interests and needs shift over the past few years. I've noticed a better control over my need for porn but it's only been a few days.
