Reached the cuckold fetish. Need help to rewrite my brain and get better. How..

I started watching porn when I was 14/15 ig. I’m 22 now..have gotten to a point where I am turned on by and interested in cuckold pornography; (which started after my girlfriend cheated on me.)

The other day I was drunk and joked with a very close female friend that we should order pizza and you should receive it bra-less/no pants (she takes these jokes well no issues) but then I realized this had gone too far.

I want to stop guys. I want to get better and be free from this nonsense.

I have stopped getting erections until stimulated by cuckold porn or some other high stimuli. Normal porn isn’t doing it now. Not just cuckold, I’ve been watching camsites(spent 200$), hentai, etc. I DONT want to do this anymore.

1) I want help regarding this ED, I sense it may be PIED 2) I want to stop this nonsense 3) how do I normalize my brain where having sex normally would still make me erect. Been a while since but I doubt normal sex would make me 100% erect 4) It’s also gotten to a point where I don’t mind not having a relationship because there’s porn and women online 5) Will AM help me in this, if so, where do I start

Appreciate any help, thank you :)
