Quick Flatline - Reboot

So about 12 days ago I couldn’t perform w my girlfriend, it was also my first time. I few thrusts was all I could manage before going soft. Now I came across nofap and was/am pretty convinced I have pied.

I think I went straight into flatline(was actively on pmo) since I already had a low libido around a week before having sex with my girlfriend which continued for about a good 4-5 days before I started getting urges again. I started getting MW which became stronger as the days went by. I got boners when I was on call w my girlfriend. I also managed to get boners here and there just from fantasising without touching my dick. A couple of nights back I was shocked to see that I had a boners from very little sexual thought which lasted about 3 minutes and that hasn’t happened in a long time since I used to lose my boners quick. So basically boners seemed to get stronger. However from yesterday I have been feeling dead down there. No libido no urge to do anything. I did still get MW - a pretty strong morning wood which lasted 10-15 minutes. Apart from that I feel dead for the last couple of days down there. Today I am on day 13 and think I’m hitting my second flatline.

Do you guys think flatlines can last only a few days and do you see this as signs of improvement???
