Best place I could really ask for this. If there's a better subreddit for more NSFW advice, please do tell me. If I need to move this post elsewhere I have no problems doing so. Alt since it's a bit embarrassing to have on my normal account.
I want to quit porn. I've been cranking my hog for the past four ish years and I believe it's beginning to have a legitimate effect on my physical health. I have a girlfriend and the porn isn't having any affect on my attraction to her- she is still very hot to me, but I worry I'm unable to really get an erection and hold it just normally. (No problems while beating it, but it doesn't stay long anymore). She knows of what I'm into (we have very similar kinks for the most part), perhaps not to the same extent for some things but generally sexually we're on the same page, at least in some broader strokes. She likely knows I watch porn, but perhaps not to the same extent/how often I do.
Currently we've not gotten sexual yet, but in the eventuality that we do, I'm terrified of not being able to perform for her. Maybe its psychosomatic but the more I think about it the more I notice it now. I don't want to have to rely on beating myself off, I want to cut off from the stuff as much as I can. This might not be the greatest place to ask but it's the only place which came to mind. Does anyone have any kind of advice they can impart onto me? Both mental and physical advice is helpful. I've heard kegel exercises can be helpful but obviously that takes consistent time. I also know going cold turkey right off the bat doesn't work. I want to be able to be there for her and work normally in the bedroom for her whenever it does happen.
