Information needed!!!!!!

I'm 20 watching porn from 14-15 and I've pied . But I've started this nofap journey for some change in my life and to cure this freaking thing .
I wanna ask some things....
1. Is watching some movie and tv series having love making scene counts as a relapse?( If I don't fap after that, I don't even get aroused by that)
2. Does sexting with the girlfriend counts as a relapse (considering that I got semihard by that chat)
3. I do have some morning woods like 2-3 in a week(not rock hard though but decent hard) .
Is this where good things starts.
4. When I have erections but as soon I stand up or roll back my foreskin it starts getting soft.(before my nofap)(is this a problem? What's the cure?)
