Trying to recover from my recent DE

Ok before I get into the story and ask you more experienced nonfappers your personal experience and success stories, I will give you a little more background about me. I started masturbating maybe around age 11 to 12 and I didn't need any kind of image or anything to O, just my imagination. As time progressed I started getting into looking at pictures in magazines and online, then slowly started getting into watching porn videos to satisfy my cravings. At first it was just normal stuff then it escalated into more hardcore things.

I've never really been that out going and looking at porn was easier than going out and finding a real girlfriend. When I would get a girlfriend or whatever and sex was an option I just couldn't perform due to being a virgin and having anxiety I guess. So I just sheltered myself and continued masturbating to porn.

Now I'm 26 and found the perfect girl who I love to death. At this point I was pretty heavy into my porn use and watching very taboo stuff and hated myself for it. It was even starting to get hard to get an erection to porn if that's even a thing. So I backed off porn and mastication for awhile before even knowing about nofap. We started to engage in sex and the first few times were bad because I couldn't keep an erection to last very long at all and I would stop. I finally was able to after a few weeks and fully have sex with her and she would actually make me O multiple times and I could keep going.

I eventually started back to watching porn due to the fact I was like "hey my penis works again" and so I masturbated away like 2-4 times a day and watching hardcore porn. Then one day she came over and we had sex and I just couldn't O no matter what and I would lose an erection due to the fact that it was just not happening, taking to long (20mins or more) and I was getting frustrated. Then it happened 2 days after that time also.

Today is September 16th and I haven't masturbated since the 12th so I'm 4 days with no masturbation and I'm in this for the long run and trying to never do it again because I don't want my sex life to suffer. I'm doing fairly well and actually haven't really felt the urge to go to porn since I have a GF. I know if I didn't have a GF I would be trying to get that rush from porn and it would be a lot harder for me to stop. But I have a very good motivation.

My question to all of you is if I refrain from masturbation will I overcome this DE problem? Am I forever doomed? Is there anyone out there that went through this that has recovered and has success stories? I've been waking up with morning wood most mornings so I think that's a good sign, but I never get spontaneous erections but I think that's just because I'm not a kid anymore but I could be wrong. Also I forgot to mention when I was having trouble getting hard to porn I didn't have any trouble getting hard for my girlfriend. Is that unusual and not heard of that much in this community? Sorry for such a long post. I just became a member and I just wanted to share my story and ask for advice and tips to beat the crap out of this DE because I love this girl and we've talked about kids in the future and I want to be able to give that to her one day. Thank you and I look forward to seeing your helpful insight and advice.
