I am now on day 7 almost 8

As a Christian, I personally see it as a relapse. The control that the urges have over me is what I'm after, which includes "releasing". I know what causes it and I want that thing to wither and die. I'm obviously still on here, so it's not dead yet lol

main focus is porn, but masturbation is some kind of stress relief

For some people it’s porn and some want the challenge of no masturbation. For me it’s porn I wanna quit and so far I haven’t gone there!

if your goal is to quit porn, it's not a relapse. if you are going no fap, it is a relapse. it depends on what your goal is. that being said, cutting down on masturbation will help, even if you don't quit it entirely
