Crazy sexual thoughts but also ED?

My situation: when doing nofap for anytime longer than a week, I will start getting crazy intense sexual desires. The sight of a hot chick will make me sooooooo horny and I would actually feel nauseas. Sometimes I even feel angry (instead of being invigorated by the sight of a hot girl, I'd just feel extremely desperate). Going to a bar/club is the worst, just the sight of a girl dancing would drive me insane, let alone 100s of them. I would keep having images of the girls I saw at the club the following day. However, when I do get a girl laying in my bed naked, even if she's hot, the situation is way different; I find it hard to get a boner/be as aroused as I was when I'm at the club. This has happened on multiple occasions. I do pop a boner but it's not very hard.

How do you deal with these thoughts generally? Do you try to just breathe and refrain from entertaining them?
Will I still experience these crazy sexual thoughts that make me feel desperate even after rebooting? Will the intensity of these thoughts decrease as I become more prone to arousal from actual touch/sensations and being present to the moment?

And going back to my situation - I came up with a few hypotheses that may explain what's going on:
1) I have porn induced erectile dysfunction/ this situation is caused by porn addiction and will get better after reboot
2) I am anticipating sex and nervous about it which gives me anxiety and leads to ED
3) When I start conversing with the girl I desexualize the moment (e.g talking to her like a friend) and don't keep things sexual, which eventually leads me to not feel aroused when she's laying in my bed.

Which one of those hypotheses do you think is the one likely contributing to the issue?

Has anyone faced something like this?
