Problems with girlfriend and dating.

To whomever takes the time to read this. I ask simply for a bit of reassurance.

I'll start off with a bit about myself and then I'll get to my problem.

I'm 24, and I've been watching porn since I was about 10 or 11 I'd say. I'm very fit, a personal trainer. I eat healthy. Keep up with the doctor visits. Lots of walking and I avoid stress as much as anybody can. I'd never say I had a problem with porn and masturbating but looking back I have probably masturbated almost every day since I first discovered porn. First from the average boy girl and then to progressively more explicit stuff. Sometimes it would take me hours to find a video I wanted. So I acknowledge I have a problem. I've been dating the most amazing person I've ever met for the past year and lately problems have been happening. When we first started dating everything was great. But I always kind of wasn't super interested in real sex. Let me rephrase that, I've always loved sex but it felt like it was missing some kind of appeal. Or that carnal desire. I've been currently dealing with pied severely lately and I'm on day 77.

So one day I heard about nofap from a friend and I made a bet with a friend to try the 90 days. I got to 73 days and relapsed. I noticed sex was a better And I was getting more morning woods. I currently get none other than when I have to pee in the morning and it's there to prevent that. The next time I tried I made it to between 45-50 days. One time near one of the last days of the 45-50 day streak I had the best sex of my life with my girlfriend. The desire was so real and I physically couldn't get enough of her. I think my Pied was apparent a bit but the desire for her was the strongest I've ever felt for someone. It was the most amazing sexual experience of my life. So what did I do? I relapsed a few days later. Now I'm on attempt number 3. Im on day 77, my pied is causing my girlfriend extreme grief because I can't get her off. And it's causing a rift between us. I've explained to her about the reboot but I think the sexual frustration is getting to her. On my last reboot around day 45-50 it seemed my libido was getting better. But now on my third try I'm quite further ahead in my reboot and I'm still not getting morning woods or any strong sexual urges. I feel like a robot sometimes. My sex drive isn't super high. I feel a bit more motivated these past few days but I'm wondering why my libido isn't like it was during my second reboot. I might be going through a flatline right now, I'm not quite sure. I just hate not being able to fully satisfy my girlfriend these past few months. The pied was severely bad about a month ago. I would get off within less than 10 seconds. Now I can go a decent amount more but it's still not enough. I never had severe pied before any of my reboots so is that common? Sometimes it's less than 10 seconds to get off even while wearing a condom. It doesn't help I'm not super sexually excited. I'm normally quite a sexually actively person too.

I guess if you've read this far my questions would be...

1. Is pied a side effect of a reboot?
2. Has anyone had a similar experience with a positive result so I can have a bit of hope
3. Any words of wisdom or hope would help this restless man who wants to please his lady.

Thank you for taking the time to read.
