I am afraid to have sex!

I am currently separated and going through a divorce so I am essentially single.

It's been 33 days nofap, and well over 4 months since I've had sex. The last time I had sex the erection was sporadic and so I know that either I have some form of ED or PIED.
Currently waking up with a semi, not fully erect. Don't know what that means but at least things are starting to get back to "normal"

Anyway, I am interested in pursuing sexual relations with a woman (no one specific in mind but open to possibilities) however I am terrified.
What things get rolling and nothing happens down there?
What if it does and I do the Charlie Runkle and last 5 seconds because it's been so long?
What if I can't complete?

I'm probably not ready that much I know. Frankly I'm just blowing off some steam here because it has been weighing heavily on my mind.

Just curious if anyone else is or has experienced this anxiety and what did you do to deal with it?
