In the past I’ve always found it easy to get hard I’m only 30 now. I am worried as the last 2 weeks I’ve not been able to get hard even when masturbating. I’ve tried the last 3 days and when I get to around 50% erect I just cum. I’m embarrassed and really worried I feel my girlfriend is worried about me as well. What do I do? Has anyone else had this happen and come out on the other side?
