The dreaded "flatline"

Im a 28 year old male looking to start this nofap journey. My biggest concern is the cursed "flatline" aka fapline. Ok I made that up. But I guess you could say I need some reassurance that this thing doesn't get out of hand and I could enjoy sex once again. I've been having some trouble getting up lately when me and my girl have sex. We've been together for about 10 years (we have 2 kids together) and I don't want her to think I'm unattracted to her. And when I do get an erection I ejaculate before she even starts moaning. It frustrates both me and her which is why I really want this to work. I'm already severely depressed and don't really have much energy or motivation so I'm afraid this might only amplify it or make it a permanent condition. I've looked on these forums and see that some of these "flatline" cases last anywhere from 2 weeks to 2 years. It also doesn't help that everyone makes it seem like it's the worst thing they ever went through. This is day 1 for me on my path to greatness after I relapsed after 4 days. The only reason I relapsed is because of this preconceived notion about the flat line. Men in today's society are defined by their sexual prowess and erections during intercourse and if I can't get the boners like I use too after this (even though I have PE and sometimes ED every now and then) it will devestate me. Anyone else out there feeling like me? Let me know because I definitely need some advice and/or feedback on how to deal with this.

 

Thanks Matt I'll look that up now
