Erectile Dysfunction

I am facing this problem from decades, as it's a taboo issue, it's really hard to find a reliable doctor or a doctor that believes me. Now I can't geta hard erection when I need to PS even I get an erection it's not hard for penetration, I don't remember the last time I got a Bonner, I don't get aehtalam and only seen getting morning wood once in a blue moon, I am really depressed, stress and in anxiety. All the help would be appreciated. I am not married.
