Not hard at all

I have been watching porn and jerking off most of my life. Super sexual person. And now that I have this app and have stopped the daily sessions I haven’t felt like I can get hard. I haven’t looked at porn or tried jerking off but I got this weird feeling like I can’t get hard even if I tried. I have tried to quite many times before but this time feels weird… I just don’t have sexual feeling recently. I have been sleeping with a girl and the last time while I was on this break, I just didn’t feel much of anything. Wasn’t turned on all that much, which I normally would have been. Also wouldn’t get very hard. I feel like I’m losing the ability to get hard. Am I going crazy or is this a normal thing with the start of a change
