Nice job of compilation. I think you hit just about all of the possibilities.
I've done some research on this and can specifically confirm #7 -- too much PGE-1.
I have confirmed this thru extensive testing and dose control. If you use PGE-1, use just enough for a decent erection. More is definitely not better.
Also, #18. Recreational drug use. Marijuana enhances sexual ability for many individuals, sometimes making orgasm more achievable. However, the same applies as above -- more is not better.

Not all on the list are "proven" some just suspected, at least by me.
I hit numbers 1 (older), 2, 3 (idiopathic in feet), 5??, 6, 7 (on occasion), 9 (shorter than ~3 days), 11??, 14 (really likes it hard and fast), 15 (Paxil once, Sudafed for sinus infections occasionally, others ???), 16/17 (@66 y/o). So I hit a lot of possible and known triggers. I can manage the latter "known" triggers. And some are unknowns including like Rx, OTC and supplements. A known common side-effect of fluoroquinolones is nerve damage and I've been on Cipro and Levaqin a lot.
Key for me at this time are time to ejaculation less than 3-4 days and higher dose of PGE1, and 14 ironically (rhythm). But one can also use that to advantage for a longer session for Wifey

but I just may not cum that time. After a month layoff on vacation with wife and two teenage grandaughters in Europe (close quarters), I am getting back up to speed and find now after a very aggressive "recovery" (every 2 1/2 days on avg)

that willey is in tuned-up shape and can actually do the job now with far less PGE1 so I am ramping the mix down. Morning wood and PHO's are quite common now.

That is a nice finding.
Thaks for all the ideas on treatments. I do L-Arginine , Propionyl-L-Carnitine, Siberian Ginseng, and am restarting Alfa Lipoic Acid for the foot neuropathy.
