Man i think i am having the same situation . I know it is definitely psychological cause it is fine in the morning erection and i feel everyday that makes me happy it is psychological and pretty hard when i watch porn and masturbate. During sex with my wife it erects but not hard enough like morning or when i watch porn . I went to doctor and he told me it’s psychological and gave me viagra which helps a lot but I don’t want to be dependent on it. I am planning to cut down porn and masturbation and my penis has lost its sense due to rubbing i guess. That is what i read on one of the post which sounds legit. I might follow the cold shower remedy from today I don’t know how long it is going to take and if it going to work or not but worth trying rather than not. Best wishes to you and like the previous dude said lets be thankful it is just psychological for us and it can be healed .
