Self help is best help. Stop masturbating until you are really sexually aroused. Have healthy diet and do some exercise. You might get counter supplement in market but there's safety is yet to be proven. Don't buy it, world is selfish and they believe in making profits rater than exposing consumer about negative effect.
Another option you may try would be to check out certain vitamins and supplements for that. I found a website where you can take an online personal health assessment and they will tell you exactly what you should be taking. I have been taking them for a little over a month now and I must say that they have made a MAJOR difference. They do include supplements that can help with ED as well. or, "sexual exhaustion".
