Recently I encountered this site: http://www.treatprematureejaculationnow.com.
They provide a free book, video and even more. I can honestly tell you that this advice has saved my marriage and it has led to the best sex we've ever had.
I was struggling with my performance in bed. More specifically, with my inability to last long enough for my wife making me feel anxious about sex.
After a while I improved my performance twice. Then I noticed that I wasn't anxious or worried about ejaculating quickly any more. Now I can last in bed as long as I want. That's why I'd like to share this information with many men as I can.
