New to nofap but have started way back on my own

I was a regular porn watcher and regular masturbater..
Sometimes i went for 3-4 times a day
Wasted all of my day
Even today i wasted all of my day(will come back to today).

So starting from my childhood i was 11-12 really dont remember..but when i saw my first porn and got too hot like extremely hot..
After that i started watching porn regularly never knew about masturbating..
Then one friend of mine told me about it
And i started doing it..
At first only white liquid use to come out
Then slowly slowly the whole bunch was there
I was very strong at that time.
Because i got a chance to have sex once (it was paid actually and still regret doing it ).
I was very good that time i use to go 40 mins straight pounding then i take it out and until i want it i won't cum.
The girl told me how late you are in this are you ok or do u have some problem..
That stuck in my mind and i started practicing daily to releive as fast as possible
Fast forward years passed by my habits remained ..
I was having trouble with nightfalls as still i was a fapper
Though i left paid sex 10 years back and waited for gf
in 2017 i met with a girl in train.
She was into me so much that she invited me for sex .
After completely leaving sex for more then 10-12 yrs..i thought i would be very good and the girl will like it ...
We started and everything was normal but after all foreplay and this and that as i went to penetrate her my tool gave up and i was so shocked at that moment
I tried 3-4 times but as i enter her i would be relived in less than 8 secs .
My world was completely broken inside me i started researching for every thing in google from doctors and etc etc...
Then i realised that the problem was me and my porn addiction and addiction to masturbate
I was fat, a smoker, and god knows what not bad things i have done to my body.
Had problem of nightfalls, erctile dysfunction, small penis in comparison to porn stars and average men, left my true world friends and was hiding behind porn and games .
My gf walked away saying opposite to what that girl said me back 12 years
"You cant hold it "
It struck me like a lightning struck a tree and breaks it into half.
I was awaken this time..
The first thing i did was stopping masturbation,
Tried stopping all the nonsense intoxicants i used to do.
And the result i got is immense till now
Nightfalls have been limited to once or twice a month
Since my stopping of masturbation started i had broke it because of loneliness sometime and did once or twice in 2 months but if i start watching porn i cant stop.
And coming to present i am watching porn from 2 days regular as it was saturday and sunday i wasted both my days but have not touched my tool once and not masturbated.
I have gone NoFap for near about 4 months
And no porn for more than 5months before today
Excluding the nightfalls i dont know if you count them or not
But today while reading on quora i saw NoFap and i thought that i will start changing my life from here.
Still i am suffering with weaker penis and pain in my leg and back nerves
but the suffering of doing it will always be more than a little suffering of saying no to both(fap and porn)
And maybe if god helps me i can fully satisfy my future gf or wife to their need and satisy myself to be a complete male ..

Thanks a ton whoever read this i have written it very fast in about 5-8 mins of time and please bear with any grammatical or any kind of mistake occuring in my post.
