Addiction and ED getting worse (Please read my story)

I have been trying to reboot my brain since December. Im 17. My longest streak has been 10 days no pmo. I never jerked off more than any one else before (maybe once a day, 5 minute sessions), but watching porn still affected me. I started watching porn to masturbate around 12, and watched it pretty much every day for years before any real experiences with girls. I got my first BJ at 15, wasnt what I expected (got soft, didnt cum). I lost my virginity that same year (which i regret) and it was also not good at all (didnt cum, couldnt stay hard). Then, besides kissing I didnt have any real sexual experiences with a girl until last summer when I was 16. I think the reason I never had a girlfriend or had more real relationships with girls by that point of my life was because porn had filled on my needs and I had no drive to get girls. I consider myself pretty good with girls and good looking, so this is unfortunate. So last summer I had one night stands with 2 girls and the same things happened with both, yet different than before. We had sex for about 20 minutes each before they started blowing me. I stayed hard the whole time but I could only cum with one of them because she blew me very fast (I have death grip too). That was the only time a girl has made me cum in my life. I was drunk both of these times. This gave me confidence for the rest of the summer, thinking that I could proform somewhat well in bed, even though I could not. Later In the summer I fell for a beautiful girl who was everything to me. On top of the great connection that we shared, she was very sexy. When It came time for us to have sex for the first time, I wasnt able to get hard. The next time we banged for 15 minutes but I couldnt cum and lost my erection. The next 10 times we tried sex were a combination of me losing my erection or me not getting hard at all. I think I had sexually anxiety with her. She took it personal and we broke up soon after. I tried to quit porn while we were dating, but after a few weeks I went back and it was like the first time watching it all over again. When we broke up I decided that I would commit to braking this habit so I can have successful relationships with women. Since then I have constantly relapsed, usually after 1-3 days. On some days when I relapse I would just say fuck it and jerk off once or twice more that same day to porn, something I never did in the past. PMO became less of a fun thing to do and more of a chore that I had to do. I think that almost everytime i have watched p since trying to quit I have thought ok this is the last time so make it good. That mentality really fucked me up. Now I dont get the random boners through out the day that I used to (not from a flatline, like the day after i pmo) and I can hardly stay erect from porn. Porn has ruined my love life for now and is making me depressed, affecting my school work. Before i tried to quit I never would jerk off twice in the same day, and I never had trouble getting boners to porn. Now I just feel like im trapped. What if my recovery takes like 6 months to a year??! Really depressing. I talk to a therapist now which helps alot but I still make the same mistakes ( I jerked off to porn today). Please share any comments thoughts or questions

By the way I have K9 blocker on my computer, and set restrictions on my ipad and iphone, all of which I dont know the passwords for. I still find porn through twitter and my xbob one internet explorer
