Hi all, in the last week, i have completely lost my erection. I dont know what the cause is. Im usually very regular and strong but since last saturday it has just disappearred. I havent injured myself that I know of and dont feel im overly stressed. Its very odd. Im not sure if i should go to the doctor or just leave it another week. Usual stimulates arent having the same effect it would normally and i can get to a semi state but it disappears almost immediately. Any advice?
