Porn Induced Erectile Dysfunction

I started out watching porn and masturbating when I was 10 or 11 years old. I didn't have a girlfriend until I was 15. The first time we tried to have sex I couldn't get an erection sufficient enough for penetration. The times after that we tried to have sex and I got a weak erection, but managed to penetrate her. I got pretty hard when I was inside but it quickly goes away when I'm not inside her. I realize what the porn and masturbation has done to me all these years so I'm unable to perform in real life situations. After reading many people in similar situations as me, I've decided to give up porn/masturbation forever to be able to perform in real situations with real girls. Summer is coming up when I will be able to go to my girlfriend's house in a little less than two months, so you know what that means. I've installed porn blockers and stopped masturbating since about four or five days ago. I feel absolutely no urge to watch porn or masturabte. Do you think I will be healed? I hate living like this and want this to be over with. If you have any questions, just ask.
