Since my 19th birthday I have been unable to get erections. For a while it seemed I couldn't get fully hard, but now I can't get it up even when I try to masturbate which isn't often at all. My mood has been okay although recently I have been a little bit stressed but this has gone on for a few months now and I'm very worried. I feel my arousal levels have plummeted too and it's scary. I don't even get morning wood.
