Looking for advice on PIED

Hi, M24
I'm describing some symptoms and looking for advice on PIED.

I've been masturbating since age of 11, not always to porn. I would say that I have been regularly masturbating to porn since last 4-5 years - 4 times a week. I'm not sexually active.

I'm not addicted to porn - as in I don't crave it too much. I can go without it for days. I have not watched it since 10th oct 2018 and I'm not having any urge to get back to it. I used to watch vanilla porn only, nothing serious. Would cum within 10-15 minute. Also I suspect that I developed DEATH GRIP as my penis would be in pain for sometime after I masturbated.

I recently had sex (my first time) with a girl but had problem getting it fully erect. I only reached 75% erection. This happened twice with the same girl. And I was not under any pressure and did not have any performance anxiety. I was unable to penetrate her initially. Even when I did penetrate her with a partial erection, I did not feel anything. It was like I had no sensation on my penis, I could not even tell if i'm inside her.

I also noticed that I don't enjoy kissing and foreplay. I do not get full erect/partially erect while I'm kissing. At first I thought that this is because I'm not attracted to the girl but this has happened with all the girls I've kissed.

I'm abstaining from masturbation since 12th October 2018 and had sex last time on 17th oct. I do have morning wood but I have low libido since then. I don't get horny and don't get random boners. I'm not craving any sex since the day I've stopped watching porn and masturbating.

I usually do push ups at home and go for walk atleast once a day. I can manage to eat healthy.

I learned about PIED on youtube and I think I have it. Please advice me on how to proceed from here now.

According to my symptoms, how much time would it take to cure my PIED and how will I know that it has been cured ?
