How long after an ED?

Hi guys, i need your thoughts on this:
I saw an escort girl like a year ago 3 times. The first two times, i had some to troubles to maintain an erection (hopefully due to my porn consumption and nothing else) but it was still good enough to perform but the last time, i couldn't perform at all, it was soft as hell, the only way i could get it up and cum is by masturbating (also, i should say that earlier that week i edged, is there any correlation?) Since then, i tried to get my life together but (as i said in this thread: https://forum.nofap.com/index.php?threads/how-to-avoid-these-triggers-triggers-warning.323854/ ) i didn't really succeed but that's not the topic.
I'd love to see her again and since the last month, i try to see her but i keep making excuses to not see her just because deep down, i'm completely afraid of not being able to get it up again.
So i have two questions for you:
-Knowing that i've masturbated 3 times today (i know, i try my best but i had kind of rough day), do you think that if i don't do it at all, i should be able to perform next week?
-Also, is there any clues that suggest that i'll be able to get it up when i'll need it or is it a complete surprise?
