I dont know the answer to this problem

Hello
I'm 25 years old and since I was a teen I very occasionally would have a stint of watching porn all night until the sun came up and even then I felt the shame and regret from how deep I got but in Hindsight, I was much more conscious then as a hormone ridden teen which is unfortunate. My teen days of browsing porn was actually very healthy and not at all out of hand despite 1 or 2 blips but it all ended when I started getting real female attention

I had a good sex life nothing obscene just a handful of relationships that flowed from one to another . It wasn't until I turned 21 I met my wife fell inove with her and did everything i had to to get her to marry me and I think during the first year was when it began what I dodged as a teen came up and bit me,

some insight to this is my wife after we got married discovered she had pcos which stripped all of her sex drive away I did the Male thing of being overly sensitive about it being something wrong with me but quickly sorted out my frame of mind I love my wife more than anything and I have made it a point not to hold it over her head ...unfortunately my sexlife was and is still all porn I know it's not healthy and I'm not a scientist but I could and would never be with anyone else so it was the only option now I'm 25 and it is getting and has been bad I feel deep shame after indulging in long sessions watching a catalog of porn being so into porn it's like a tv show and I know all the cast all there scenes etc.

My triggers have become so sensitive I feel like I cant go anywhere watch any thing no movie or tv show even commercials are teeming with hyper sexualized women waving it around in front of my face ( I'm not being a prude as a intelligent human i know this is a good thing for women to own there sexuality) but i cant escape it and it triggers me i spend at least 3_4 hours watching pornography and edging I actually became so familiar and bored with my favorite celeb crushes and pornstars I had to get other porn watchers to show me new models to keep it fresh
I recently watched a porncast that was hosted online mainly do and gang bang popular stars I watched from 6 PM til 10 am searching and holding out for the perfect climax I was home alone when I do this and I do get lonely so my self analysis is i try and fill up all my time doing that cause i dont wan tv to remember I'm alone I'm no doctor though
And the 3 days in a row before that I was doing 12 to 5 am

I hate how it makes me feel what happens when I run out of stimulant I'm 25 and heading down this road so far I'm blessed to be fairly vanilla by today's standards but I'm going to be with my wife forever because I cant live without her I just want to be a good man not riddled with shame self loathing as I dig a deep perverse whole for myself but short of chemical castration I dont think I can keep porn in my life because I will lose control and indulge in long sessions so I dnt think I can balance it healthily in moderation...

I really need some help.
