Nancy, could you explain me details about erection dysfunctions? How does it happen and how to cure it?

There are a lot of physical and psychological causes of erectile dysfunction. Reduced blood flow to the penis and nerve damage are the most common physical causes. Underlying conditions related to erectile dysfunction include the following:

1. Vascular disease
2. Diabetes
3. Drugs
4. Hormone disorders
5. Neurologic conditions
6. Pelvic trauma, surgery, radiation therapy
7. Peyronie's disease
8. Venous leak
9. Psychological conditions

So, it is always my advice that you see a doctor first, so you can narrow down why you are having erectile dysfunction. As far as treatment for erectile dysfunction:

Sex Therapy
A significant number of men develop impotence from psychological causes that can be overcome.

Medical Treatment

1. Oral Medications like Viagra or Levitra.
2. Self-Injection to produce erections for about a half-hour.
3. Penis pumps can help produce erections in men who are already able to get a semi.

I hope this helps. My first advice is to see a professional to understand why the erectile dysfunction is occurring.
