Nofap with a long term girlfriend?

A little background then, I am 24 and have been addicted to PMO since I can remember, probably started age 10+, I got my first handjob and ever since then I loved the feeling. Growing up I used to fap to anything I could get my hands on (magazine wise) because the internet wasn't really big here, but when I got older and found the internet *porn* then it got serious, I was doing it 3-4 times a day probably, I joined the military and shared a room with 10 people but it didn't stop me going to the bathroom at 2-3am to rub one out, I done it in porto-potties while even on exercise it was that bad, I was having sex at the same time but most of it didn't satisfy what I had been watching online (some kinky stuff), I started experimenting as much as I could but sometimes it just wasn't enough but I made do, I fantasised about sex all the time, I couldn't walk down the street without thinking sexual thoughts about every women that walked past, not in a creepy way where I would stare at them up and down it was quite the opposite, it made me shy around women to the point I thought maybe they know what I am thinking, it got in my head and made me awkward around girls but again I made do, I met my partner about 4 years ago and it started out the way all my encounters with women did... sex ( I'm not confident at all, again quite the opposite I hate myself and think I am the ugliest guy in the world) so whenever women showed an interest in me I fell for it because of the lack of self-confidence, theres probably another side to why I was a bit more kinkier than the average dude (abuse when I was younger) but that isn't really relevant.

So we started dating and at first it was just sex because she lived 400 miles away where I am from but because I was based elsewhere it worked, but when we started going out it got hard because I couldn't kick the habit of having these sexual thoughts over everyone and it made it difficult to have a girlfriend because my mind would constantly wander when it came to other women ( I felt really bad for feeling like this )

We have tried basically all the kinky fantasies I have wanted to try and now part of me feels like sex is just mundane and boring because to an extent I have done it all..... but not when I watch porn, I currently watch it while she is at work and at night when she is asleep, she doesn't think I am attracted to her anymore when I am it's just I get horny when she is at work and rub one out. I still can't shake the thoughts of sleeping with other women (celebrities and what not) and it is really having a massive affect/effect *spelling was never my strongpoint* on our relationship so I wanted to quit the fapping and try get rid of the mindset I have.

I have told her sort of everything, I told her that I had/have a sex addiction and I think about the things I think about, I am going to tell her tonight about my porn addiction and try talk to her about it.

I guess I am looking for tips and if while doing Nofap can you still have sex with your SO or is it a bad idea? I don't want to live like this anymore, I wanna be happy and healthy, it is impacting my mental health too so I do want to change my ways. My therapist has explained to me that part of the reason why I am like this sexually is because when I was abused it kinda put me in a hamsters wheel of sexual thoughts, something that every teenager goes through but the issue is I never got off the hamster wheel and everyone else did.
Sorry for the long post and thanks for reading.

 

I have spoken with her about it and she is willing to do hard mode if it is going to help, it is just going to be hard to fight the addictions now.
