ED since 15 and still now at 37

So last night I came across Nofap on accident, read loads and loads and decided enough is enough and it's time to to get my life back and get laid..... With out Kamagra.
When I was really young, I remember having the strongest erections, rubbing myself on the mattress and O, even walking around doing my paper round with a constant erection hoping some Milf would answer the door.
Well this all disappeared somehow over night and from the age of 15 to my age now of 37 I have been unable to get an erection with a girl.
I always blamed cannabis for this as I started smoking it socially when I was 14 but quit when I was 21 due to major paranoia.
I am someone who has always been in trouble with the law, fighting, drunk, anti social behaviour etc and now after reading posts 100% believe that excessive M watching P may be the cause of all this and all my failed relationships where my girlfriends totally have enough of my regular isolation needs and strong principles.
I have been M since I can remember, it was all normal, mesmerised by women like sharon stone and pamela Anderson wanking off to films and pictures in magazines. As time went on it got easier and easier getting hold of P videos and always found myself seeking more extreme P than the last. I hate to admit it but one day I came across a BBC and was so mesmorised by I still think about it everyday and I'm not even gay. At first it was just like wow, look at him the lucky fucker, at 1St I just liked watching them fuck white women but over time I started wishing I was the woman servicing the BBC and it got worse when I first had the Internet when I was 27 coz Porn has just escalated it so much making me seek harder and harder P that to this day I am watching interracial P, cuckold P, sissy hypno p, gay p and transvestite p and it's crazy because if you ever met me you would say I was one of the manliest men you'd ever met.
This is I'm sorry to say has ruined my sex life. Although I have a great sex life o can't get an erection without Kamagra (which has saved my life) and cannot O with out thinking of my girlfriend sucking and fucking BBC.
I even met a black guy online and slept with him and I'm not even gay and this is all down to Porn, the funny thing is that when I was shagging him I was thinking about women, work that one out, fucked up or what?
I really need to over come this and be a happy person, no M starts today, with no alcohol and better food, wish me luck
