Porn Induced Ed

Hi, I am an 18 year old male, who has recently has a porn and masturbation addiction for about the past 8 months. I would masturbation 1 to 4 times day depending on how i felt, before then i would rarely masturbate maybe once every couple of months. Since my addiction i notice that my erections got weaker, and every time me and my girlfriend tried to have sex, i couldn't get hard and had lack of sex drive! So i did some research on why this is happening to me and i came across a video called your brain on porn. It told me i has rewired my brain and the only way to go back to normal is if i stop p&m for awhile...So I recently have stopped masturbating and looking at porn for a month now. I have been getting a lot better and stronger erections, i feel like my sex drive is slowly coming back, but still not quite there yet! But I was wondering if it was okay to look at porn and masturbate just once every month, or would that still rewire my brain!?
