Day 4 and idk what is happening

Hey guys, I'm on day 4 of this journey and I am already really confused.
This is my story:
I am 21
I used porn to masturbate at least 3 to 4 times a day for at least 6 years. I am in an amazing relationship for 6 months but somehow I wouldn't get hard from a kiss or even making out, it always needed actions down there to get it up. So I struggled with getting hard but especially maintaining a hard on...
I always thought it was simply how my dick is or works until just recently as I came across an article about NoFap and Porn Addiction. Getting more into the topic I could tick more and more boxes and was left with a weird feeling of "Fuck I think I actually do have a problem. A severe addiction even."
So I decided to give it a try and completely cut out porn and masturbation. Now I have read a lot about PMO and also quitting orgasms for a while in addition. But somehow I couldn't find an answer to whether keep have sex with my partner or not. And also if I do have Sex, whether to O or not. I do have to add though that we see each other only on the weekend which means 5 days of strict PMO and the weekend only Os.

As I mentioned before I am now on day 4 and really don't feel anything changing in a positive way. I expected to feel good about myself and energized. But in reality I feel bad. Like bad about myself, the way I look and I am kind of angry all the time and very easily irritated.
Sometimes the urge to fap pops up but so far I am handling it quite well.
What I'm not handling so well is all this confusion and the questions I have left regarding my relationship...
Thank you guys, I appreciate all the help I can get!
