Hello dear... Regarding the problem of erectile dysfunction, it is caused by reduction of blood flow to the penis. It s mostly related to anxiety that whether you will be able to perform or not. So...don t worry about all this & stay relaxed during intercourse. Performance can be improved by taking a diet rich in fruits, vegetables, fish, nuts & honey. You can also do oil massage of the penis...it increases blood flow & maintains the erection. Avoid smoking & alcohol. One more thing...avoid consuming any over the counter medication which claim to improve performance...it may be harmful. Best thing is to eat a healthy diet, exercise regularly, avoid stress, get good sleep, think positive and stay happy. Wishing you a Healthy Life. Take care
