ED and PE problems discussion

So personally I've had ED for quite a while. I feel like my PE is my body trying to orgasm as quick as possible since it's not sure how long the erection can be maintained.
I've laid next to beautiful girls being into it mentally and my dick just not working. The only time it really works is in the morning when I just woke up. And those times I did get it in while kind of hard I came pretty quick.

Have the same issue when I masturbate. I'm not that into it and try my darn hardest to stay/get hard and I get close to erection quickly suddenly (sometimes even involuntarily O). While the few times I do get hard properly I last pretty well during M.

The things I currently feel could be the issue(s) are:
- low testosterone.
- PMO addiction
- bad blood flow
- mental issues
- bad diet/bad sleep.
- tight/weak pelvic floor

After failing my last streak my erection quality was a bit better for a while. But I got sick and it has been back to the low quality days ever since. I'm trying for a streak again but it's been hard to get one going again.

How has your experience been with PE/ED? Did nofap cure it? Did anything else to fix it or still struggling with it?
