Is nofap enough?

Hi guys and gals!

My story, probably just like the rest of you.
30 years old dude, that cannot maintain an erection when having sex with a real person.
I remember 10 years ago when I had no issue with that and could go on for hour.

The issue? I think it's death grip, porn overuse and performance anxiety... I think.
A little background about me.
As I said, 30, in great shape - I do weight lifting and have a very active lifestyle - I don't have any issues with my confidence and stuff like that, and it may sound a little douchey but I know that if I like a girl there is little to stop me to get a relationship with her - if I want.
So yeah, no issues there, porn hadn't affected this yet.

What it has affected is the ability to maintain an erection while having sex.
I have been abused porn and masturbation for over a decade - fapping 4 times per day is the average for me.
During most of this time I was in a relationship with a smoking hot girl and I had to pop up a bottle of tianli when I thought we were going to have sex...to maintain an erection.
She never knew. And our sex life was pretty shitty because of that - I always avoided spontaneous sex - and over the years it became nonexistent.

Back then I thought there is just some medical issue with me but now I don't think this is the case anymore.
I can get erections and maintain them even after orgasming to the point of another consecutive orgasm...during solo porn session - I put this on the weightlifting part: it really helps the plumbing

Recently I got into another relationship with an awesome girl and 50% out of the times we had sex, not even the tianli shit worked (also, I do not recommend that stuff, god knows what's in it), it only worked when I tried not fapping for a week.

After sabotaging the relationship and finding out about nofap and yourbrainonporn I'm pretty sure I have PIED and death grip + some performance anxiety because of the two.

About a week and a half ago I decided to start...but I succumbed to my urges after 8 days.
That's when i did a full purge of all porn related stuff I have and I am starting anew.

The thing is, I get the urge to remember and fantasize about the last girl I was in a relationship with - is this ok or I should cut this off too?
And to my question, is nofap going to cure my PIED?
Or is this not enough and what I really need is to find a partner, explain them all the issues I have and work things out together, like a couple sex therapy or something?

 

Thanks man!
Yeah, even now, after 3 days without masturbating and 11 without porn I can feel some changes...like I can get an erection just thinking my ex girlfriend - something that was impossible before.
Also, I am a bit of a nihilist and antisocial person - I don't really want to be around other people, and I think PMO has a lot to do with this.
Since I started I'm beginning to reconsider my social needs.

I am determined to quit porn forever!

 

Thanks man!
Yeah, the healthy lifestyle is pretty much covered - I do bmx, I run with my dog daily (perks of having a dog) and powerlifting. And I have a balanced diet, not smoking, alcohol or other drugs.
I'm pretty sure it's all mentally because on my own (with porn) I could masturbate, have an orgasm and my penis would not go soft - I kid you not - as is nothing happened and it was ready to go.

But as soon as I am with a girl...after the initial erection I get when we start kissing...it's all downhill
