First, welcome man. It's a good thing that you're here. There's a lot of different opinions on the site, but for what it's worth I'd suggest that the best reason for giving up masturbation is that you're removing it's ability to screw you up later. The nature of the thing is that it tends to escalate and get addictive, so while you might not be all broken now I promise you (as a 40+yo porn addict with a wife and kids) that it is not a road you want to go down. I did. Lots of guys here did, and it's destroying lives. You'll be saving yourself so much grief to just walk away from it now.
Look, I don't want to scare you, it sounds like you are doing all the right stuff and coming here and everything, but you need to take this stuff seriously.
It's a really supportive community here, and we'll all try and help. Bless you man.
