Figuring this out as I go

Good afternoon, everyone.

So, I am in the early stages of a new potential relationship. I have been single for a few years, and I have not had sexual intercourse during this time. I have relied heavily on pornography and masturbation. And I'm learning the hard way (sorry no pun intended) that this may have had some detrimental effects on my erectile function. It's a fairly overwhelming feeling, especially because I've met someone that I like who is very sexual in nature. Not really sure how this is going to go, but I'm going to do my best to thread the needle and make the best of my ability to satisfy her. My plan right now is to use the following strategies:
No porn, no masturbation
Regular exercise including cardio and resistance training
Supplementing with appropriate vitamins and minerals, eating healthy, etc.
And so much of it is mental. I'm feeling a little overwhelmed thinking in this moment about the irony of reaching this point where, after spending a lot of time on my own trying to become my "best self" for the time when I wanted to be with the right woman, I've been making decisions that were so detrimental. I believe in Law of Attraction and the power of mindset, so it will not serve me to reflect on how this *might* not go well, but rather I also will meditate on and visualize the kind of satisfying relationship I want to have with this woman.
So, this post is essentially me taking the first step in recognizing that things aren't the way I want, and looking for any encouragement and positive support that you all can share.
