Erectile dysfunction can be due to either psychological or physiological causes. Psychological causes are when men get anxious about the impending performance – basically stage fright. This can be affected by many things such as perceived inadequacy, as with Small Penis Syndrome, or just a previously awkward rendezvous. If you are suffering from premature ejaculation or think you should maintain an erection longer talk to your partner and consider talking to your doctor.
Medical causes of erectile dysfunction are numerous but include such things as diabetes, hypertension, smoking and alcohol consumption. In most cases, erectile dysfunction is reversible, and men can regain their normal function if they ask for help. If you have any concerns talk to your doctor.
The website emedicine.com, like most reliable resources, emphasizes that smoking is a high risk behavior that often leads to erectile dysfunction. There are many many reasons to stop smoking, but knowing it may alter the normal function of your penis should help spark you to visit your doctor and ask for help.
