How Can I Cure ED Naturally and Permanently?

Question:

For the past year or so, it’s been increasingly difficult for me to get an erection, or if I get one, it never seems to last long enough to complete sexual intercourse.

I know that I can pop Viagra or another ED drug to get a few hours of relief, but is there any way that I could cure myself of this impotence?

It’s beginning to have a very negative effect on my marriage and my happiness. Gary O., Thomaston, GA
