First Step Towards Self Improvement

I’m 20 years old, and in great need of change. Since I was 10/11 years old I’ve been masturbating to some form of pornography or another. As early as the age 13 I got into some really twisted subsections of pornography. This landed me with a fetish that chips away at my self esteem, and is extremely poisonous to the serious romantic relationships I’ve had. I’ve tried nofap before but never really made it past 3 or 4 days. I want to free myself of this. I want to be proud of myself even when no ones looking. I have no reason not to be confident in everything I do if it weren’t for this disgusting compulsive monkey on my back with a grotesque sexual appetite. It seems I always have some excuse or another to jerk it once again and fall back into a destructive pattern. Does anyone have any tips, or can offer accountability in my journey. I wish y’all the best. I am fortunate this community exists because I never can quite feel comfortable talking about this issue with others.
