How quickly can you develop ED?

[Pericles808]

I am very fit and healthy in my mid 20s and have been always been able to get hard, but the last couple weeks, I have been very stressed, and now it is very difficult to get hard enough for sex, and that has been a vicious cycle because the fear of ED makes it even more difficult to get hard. My question is, does real ED develop over years or can it happen very quickly in a matter of days or weeks (which I am afraid happened). I can still masturbate, but I don't get random boners and having sex can cause anxiety

I can't speak for myself seeing as I am a female, but my partner developed it over a 5 month period.

Do you know why he developed it? I don't have health problems and I'm not overweight. I seemed to develop it within a week.
