I'm in my late 30s and have never had a problem getting it up or going for a long time. A couple months ago I went on a bit of a bender ending with a night of too much booze and weed. The next day it was like my mind snapped and my dick died. After a week I got out of the mental funk I was in but my dick hasn't fully recovered.
I can still get hard, but it takes a while and some in the moment coaxing. Not guaranteed. Also I can only stay hard for like 10 min, then need like a 5 min break before I can keep going. Same during sex or while jerking it. I still get morning wood, but not always.
I know things like background stress can affect you, but it was like a sudden off switch one day with only partial recovery.
Any thoughts?
