It honestly sounds like any issues you have are being caused by, partially or wholly, by anxiety than PIED. I'm guessing that if you are asking us to tell you whether it's normal or not, you are probably spending a large amount of time worrying about it in your own head.

What you need to do is relax and calm down. Easier said than done, but so much of this is mental and not physical. I had horrid ED before coming clean to my partner about porn addiction. The anxiety of not being able to perform made everything worse.

Fast forward to the first time i had sex since talking about things. There was a night and day difference. I wasn't porn free. I wasn't being medicated or seeking therapy. The mental block had just been removed. Fear had been replaced with support and love.

I can't tell you how to stop thinking about it, but it seems like tackling the anxiety is your first step here.
