I have encountered sexual performance problems as well. I have been on the hunt for a cure. Well, I have been looking into variouis herbs that increase circulation, excitement, etc... and you should look into Yohimbe, ashwaghanda, hobiscus, damiana and lactus for a start. I think, but not positive, that several of these increase circulation to the genital area. Best advice is RESEARCH! try to treat the cause and not the symptom. i like the idea of letting the body heal the body or heal it naturally and not pharmecutically.
